Here are my current personal forecast thoughts for far southern Illinois and western Kentucky...
Thursday night: Becoming cloudy with a chance for showers and thunderstorms before midnight and then showers and thunderstorms likelyafter midnight - lows in the upper 40s. Southwest winds becoming northwest at 10-15 mph.
Friday: Raw - colder - windy - a period or two of rain showers - rain. Highs:mainly in the 40s Wind: Northwest/north winds 10-25mph and gusty Precipitation probability - 60%-80%| Rainfall totals: 0.30-0.60" Confidence in this forecast is high Forecast for your local town/city - Click Here
Friday night: Some clouds early with a slight chance for showers over our eastern counties. Otherwise becoming mostly clear and colder
Lows: in the middle to upper 30s Wind: North winds at 10-15 mph Precipitation probability - 10%| Rainfall totals: 0.10" Confidence in this forecast is very high
.
Saturday:Partly sunny and colder.
Highs: in the middle 50s Wind: Northerly winds at 10-20 mph - gusty Precipitation probability
- 0% | Rainfall totals: 0" Confidence in this forecast is high
Saturday night: Colder with a chance for frost - clear sky conditions
Lows: in the 28-35 degree range Wind: North winds at 10 mph Precipitation probability
- 0% | Rainfall totals: 0" Confidence in this forecast is high

HEADLINES: Our warm weather will soon come to an end. A strong cold front is approaching our region from the west. This front will move into our area by Thursday night and Friday morning. As it moves into the region it will spark showers and perhaps a few thunderstorms. Severe weather is not anticipated.
Rain showers will push through mainly Friday morning - afternoon hours may bring lingering right or light rain - gusty winds.
Let's take a look at temperatures ahead of and behind the front - this map is from Thursday morning. Can you find the cold front? :)
This is what the weather map looked like on Thursday afternoon and evening - check out the snow on the back side of the storm.
The cold front will sweep through the area early on Friday morning. Light rain will continue well behind the front. Rainfall amounts should be in the 0.30"-0.60" range. It will be a cold/raw/windy day on Friday - not very nice for any outdoor events.
Temperatures will be falling on Thursday night into Friday morning - temperatures will never recover on Friday. Clouds and rain showers - cold northerly winds - all will combine to keep temperatures in the 50s.
By Friday night the cold front will be to our east and showers will come to an end. Right now it appears the majority of the showers should be to our east by sunset. There is a chance a few showers may linger over our eastern counties into the early evening hours. Most of us will be dry, however, by dusk.
Temperatures on Friday into early next week will be below normal.
Bottom line - it is going to turn colder - clouds and some rain on Friday. Frost will be possible on Sunday morning - Monday morning - Tuesday morning. A bit unsure about Wednesday morning. We will also have to watch and see just how large the east coast storm ends up being. This will have an impact on our temperatures, as well.
Winds on Friday will be gusty out of the northwest and north - speeds in the 10-20 mph will be common - higher gusts possible.
Winds on Saturday will also be gusty - boaters use caution on both Friday and Saturday.
Winds may continue to be gusty into next week as the big storm winds up to our east.
You can see from these high temperature maps how much temperatures will fall - the first map is Thursday afternoon and the second map is Saturday. Nice drop off in temperatures.
And here is the map for Saturday's high temperatures
Lows on Tuesday and Wednesday morning might be colder than official forecasts - this is because of the big storm in the east pulling down colder air. The GFS is showing hints of this - freeze for our region? Possible.
First images would be for Tuesday morning and second image would be for Wednesday morning (low temperatures)

Of course the big story for the United States will be where does Sandy head over the coming days. Hurricane Sandy is currently moving northward through the Caribbean and will soon approach the Florida coastline. Sandy should stay just offshore of Florida. High swells, heavy rain, and gusty winds are likely along the Florida Coastline.
As Sandy continues to move north it will start to interact with the storm system that will move through our region on Friday. That means that the system could intensify even further and coast major problems for portions of the Middle Atlantic into New England. Anyone with family or friends in those areas should tell them to closely monitor weather updates over the coming days. Sandy will not impact our region. The concern is to our east. We may see some windier conditions or cooler temperatures because of the strong northwest flow accompanying the system. This is what Sandy looked like as it crossed the islands
The above image was from Wednesday afternoon. Let's take a look at Sandy on Thursday morning (early AM hours)
Click image for a LARGER view This first image is the water vapor view - the second image is an infrared satellite view
Hurricane Sandy
hit the southeastern tip of Jamaica near 3:20 pm EDT this afternoon, as
a Category 1 hurricane with 80 mph winds and a 973 mb pressure.
According to NOAA's Historical Hurricane Tracks website, Sandy is the thirteenth hurricane to make a direct hit on the island, and the first since Hurricane Gilbert of 1988. Kingston, Jamaica
recorded sustained winds of 44 mph and a pressure of 972 mb in the west
eyewall of Sandy at 4 pm EDT. The eastern tip of Jamaica will see the
strongest winds of the right-front quadrant and the heaviest damage,
though. A distorted eye is apparent on visible satellite loops, but Sandy is showing only minor disruption to its inner core structure as a result of hitting Jamaica. According to the Jamaica Observer, "Alligator
Pond [in St Elizabeth] was inundated with the high waves that came
ashore. We are now getting reports of impacts out in St. Catherine,
Portland and St. Thomas as the ground becomes saturated. We are now
seeing where light poles are toppling and landslides being reported and
roadway being flooded to the point where there is impeded access in east
St. Thomas." Heavy rains from Sandy are falling in Haiti. A NOAA
forecast based on microwave satellite data predicts 12 inches of rain
for the tip of Haiti's southwestern Peninsula, which will likely cause
life-threatening flash flooding. Fortunately, much lighter rainfall
amounts are predicted for the capital of Port-au-Prince, where 350,000
people still live in the open under tarps in the wake of the January
2010 earthquake. In August, flooding from Hurricane Isaac killed at
least 29 people in Haiti.
End of his comments
Here is the GFS model from www.wright-weather.com
Remember that the GFS is just one of many models that meteorologists use to forecast the weather. You can see Sandy moving up the coast and becoming entangled with the trough of low pressure moving through the northeast - this could be a significant event for the coastline area. High winds, major flooding, heavy rain, and even snow in some areas inland. The potential for a damaging event appears to be growing. With that said - questioned remain on the exact track and eventual strength of Sandy and perhaps the merger.
The first image is for Sunday night - then Tuesday night - then Wednesday night - you can see the system TIGHTLY wound up and moving northward
Click images for the real size view - the colors represent heavy rainfall - the deeper colors are the heaviest rain. The lines are isobars. The tighter those isobars are the higher the wind speeds that can be expected.
Then Tuesday night
Then Wednesday night
New data indicates a landfall further south - models will continue to go back and forth with the eventual path and intensity - LONG way to go to monitor this one.
Here is the morning run of the GFS model - see how it has shifted landfall further south
Here are some thoughts from another meteorologist concerning the big storm for the northeast - again still a bit early to make a forecast on eventual landfall - but the statement below gives you some idea of the potential of damage.
With some models now showing Sandy making landfall well to the south of New England,
and possibly meaning less of an impact to New England, something keep in mind, esp
for wind potential...
The Dec 11-12 1992 event...one of the worst Nor'easters on record to impact NEUS/Mid
Atlantic. The storm central pressure got to down 985 mb near the Delmarva and stalled. We
had a 1035 mb high over Quebec and it was bad for wind BOS to DCA. Maps here:
Now the ECMWF shows a similar depth high to the NE-NW. Its position is further N and
it isn't as strongly nosed down close from the NE like in Dec 92, *but*, do some math here.
What was the absolute pressure difference then?...50 mb. What is will be the absolute pressure
difference coming up...being a bit conservative at 960 mb for Sandy, and the 1035 mb high
the ECMWF shows...75 mb! The high to the N is not as pressing for the Sandy event, but a
25 mb greater difference I would think would make it at least as bad as Dec 92 for wind/storm
surge in New England, given the track stays to the S of Long island. So a Delmarva landfall might
not make much difference. Problem is impact is going to be high regardless so any minimizing
statements (i.e. not the worst case scenario) might not be a good idea right now. You have to
look at it from degrees of bad. Even if it is not the absolute worst case scenario for New England, the
worst case scenario is so bad, that getting a little less than that is still really bad relatively speaking.
So if only a million people are w/o power in in southern New England vs. 1.5 million...see what I mean? When that many people lose power, it is a disaster no matter what.
The infamous Blizzard of 78 in New England had 70-73 mb difference between the high to the N
and the storm center to the S of New England.
Here is my summary of day 1 of the Dec 1992 event from my historical wx files. We got hit hard in SNE obviously as well.
12/11/1992
One of the fiercest "nor'easters" this century in was progress
across the New York City area and the Mid Atlantic region. A
985 millibar low stalled over the Delmarva Peninsula. This
combined with a 1035 millibar high pressure over Quebec set up
an enormous easterly pressure gradient which resulted in winds
exceeding hurricane force in many places and record high tides.
Ambrose Light Station just southeast of New York City recorded
sustained winds of 80 mph with gusts to 93 mph. Wildwood
Crest, New Jersey reported gusts to 90 mph and New Holland,
Pennsylvania measured 82 mph gusts. In Philadelphia,
Pennsylvania, the high winds broke a church steeple which fell
onto and closed the Ben Franklin Bridge to New Jersey. Some of
the worst coastal flooding ever associated with a nor'easter
occurred as tides were pushed 3 to 6 feet above normal,
resulting in widespread damage and beach erosion. LaGuardia
Airport was closed due to flooding. The East River flooded
Manhattan's FDR Drive, stranding dozens of motorists. Flooding
at a Con Edison station shut down New York City's entire subway
system for more than 3 hours. Tremendous snowfalls occurred at
inland locations as the storm was a very slow mover. Piney
Dam, Maryland was buried under 42 inches of snow to set a new
state snowfall record for a single storm. Ogletown, Pennsylvania
measured 36 inches of snow and Mount Storm, West Virginia recorded
32 inches.
End of his comments - you can see there is great concern about coastal flooding and other problems from Sandy.
Back to our region... Normal high temperatures for this time of the year - see map below
Normal lows for this time of the year
Gusty winds and rain on Friday will make it feel raw outside. Otherwise - some frost possible Sunday, Monday, and Tuesday morning.
If you have sensitive plants outside then monitor overnight low forecasts in the coming days.

1. The big story in the extended range will be the looming threat of a major storm along the East Coast of the United States.
For our region we will experience below normal temperatures into the middle of next week. No severe weather is expected in our local counties through next Tuesday. I will be monitoring the potential for some severe weather as we move into the first week or two of November. Long way off - monitor updates.
This is what the GFS is showing for November 5th and 6th - LONG way off but the signals have been on the maps for awhile. This could bring showers and thunderstorms into our region. I will be keeping an eye on this storm system.

HEADLINES: The big story in the coming days is going to be the storm moving up along the eastern seaboard of the United States.
Tropical Storm Sandy is currently located south of Jamaica and is moving northward. Sandy will eventually become a hurricane and bring very heavy rainfall to the islands - flooding rains.
A trough of low pressure will move through our region on Thursday night into Friday night. This trough will bring a cold front into our local counties during the day on Friday. A band of showers and thunderstorms will form along the front - rainfall totals in our region should be on the light side. Severe weather is not currently forecasted with the cold front.
As the trough of low pressure moves east over the weekend it may combine with Sandy and become a powerful system. Some of the model data indicates a historic storm hitting portions of the Middle Atlantic and New England region. Those with interests along the East Coast of the United States should monitor updates in the coming days.
This is what the NAM Computer Model is showing for Sandy on Sunday. You can see it off the coast of Florida. You can also see on this map the cold front moving through our region. That would be the pink and purple area - the pink and purple indicates rainfall. See the scale at the bottom of the page.
Nothing too heavy for our region - but some showers and storms. Rainfall totals will likely be in the 0.40-0.80" range. Friday will turn much cooler and windy - raw fallish day.
Click image for full size view - image is from www.wright-weather.com
Let's take a look at what the GFS Computer Model is showing for Sunday - same time frame. Similar track - GFS (at this point) is a tad east of the NAM Model.
By Sunday morning the GFS has the system well off the East Coast of the United States - however, other models pull it further west. This will need to be monitored in the coming days. If this system does merge with the trough in the central United States then it will be one heck of a storm.
Look at what the European does with the storm - another model. It brings it well west and impacts New England with a devastating blow.
This image is from WeatherBell
Here is the GFS model low temperatures for Sunday and Monday morning - brr - part of these lows depend on the eventual track of our storm along the eastern seaboard.
I will need to fine tune the actual forecast lows as we move through the work week. If you have sensitive plants then you might pay a little more attention to forecast updates over the coming days.
Click image for real size view - image from www.wright-weather.com
Sunday morning lows
And then Monday morning lows
Here is what Sandy looks like on Satellite (as of Tuesday evening)
If Sandy fully merges with the trough of low pressure then we may experience even colder air than forecast for Sunday into the middle of next week. Perhaps our first hard freeze. Stay tuned.
