About a week ago I posted on Facebook that parts of our region will likely see anywhere from 4-7 inches of rain before the end of the month.  That appears to have been underplayed a bit - if I had to say it over again I might say parts of our region would experience anywhere from 7--10 inches of rain.
.
Many of us picked up 2-4" of rain over the last few days - I believe we will also experience another 1-2" with locally higher amounts on Sunday through Tuesday night/Wednesday morning - then a couple of more systems after that.  All said and done - some heavy totals.

.
We have a nice couple of days ahead of us.  Friday will be a bit on the cool side but it will be dry.  Saturday will be dry during the day.  Temperatures will warm a bit in advance of our next storm system moving in from the west.
.
Saturday should be a GREAT shopping day in the region - for those looking for holiday gifts.  Take advantage of the nice weather.  It will be windy - boaters use caution.
.
Here is the wind forecast map for Saturday - map from www.wright-weather.com - click image for real view size.
.


.
Showers and some thunderstorms will be possible on and off from late Saturday night into Wednesday. I am watching a couple of storm systems for this time period.
.
Right now it appears that a general light to perhaps moderate rain event will occur late on Saturday night and last into Sunday night.  Thinking right now that rainfall totals during that time period could be in the 0.30-0.50" range with some areas picking up a bit more.
.
Then there should be a lull in precipitation at some point on Sunday night/Monday morning - then another round of precipitation develops Monday night into Wednesday.  Depending on the track of the storm system some of this rain could be heavy.  This is especially true for the Tuesday and Tuesday night time frame.  Again - several days away and plenty of time to monitor.  Some of the data is indicating rainfall totals in excess of 1".  
.
I will fine tune the timing of the precipitation as we move forward into the weekend. 
.
Remember how I have told you that when the pressure graident tightens up our winds increase.  Equal lines of barometric pressure are called isobars.  You can see on this NAM Model forecast below where the isobars - those whitish lines - tighten up on Saturday (especially over Missouri during the time frame on this image).  What does this mean?  Breezy conditions!

.
Here is the wind forecast for Saturday - the scale is at the bottom of the page.  You can see where the strong winds are - then compare to the map above where it shows the isobars.  Tighter=stronger winds.
.


.
Here are the precipitation maps from my web-site.  It won't rain every hour of every day - but you get the general idea.  There will be increasing chances of rain from Saturday night into Wednesday.  SATURDAY during the day - WILL be dry :) - ENJOY!!!

Thanksgiving will be dry and cool.

Date Range:  November 20th -November 23rd
Event:  Unsettled with several periods of showers and thunderstorms - locally heavy rain.  Windy at times.
Severe Risk:  Low
Frozen Precipitation Risk:  None
Details:  Appears wet with several low pressure areas in the central United States 
Confidence in my forecastVery High
.
.
Date Range:  November 25th -December 2nd
Event:  Active weather pattern - we will be between the cold air to the north and warm air to the south - multiple storm systems may bring several chances for showers and thunderstorms - occasional shots of cold air - cold air is building in Canada.  Expect several significant cold waves towards the end of the month into first part of December.
Severe Risk: Too soon to make a forecast on severe weather - locally heavy rain is possible
Frozen Precipitation Risk:  Unknown - too soon to make a call on that
Details:  Potential for occasional shots of cold air with an active pattern - will be near the boundary of cold/warm air - plenty of chances for rain and possible thunderstorms. 
Confidence in my forecastHigh



.
Date Range:  November 28th -December 8th
Event:  Below normal temperatures.
Severe Risk:
Frozen Precipitation Risk:  Unknown
Details:  I continue to watch the cold air building up north - the pattern favors a dump of cold air towards the end of the month or into the beginning of December.  Unsettled pattern overall for the next three weeks.  Wet with numerous systems producing rain and thunderstorm chances.
Confidence in my forecast:  Low

.

.
Date Range:  December 3rd - 5th
Event:  Below normal temperatures.
Severe Risk:  
Frozen Precipitation Risk
Details:  Potential precipitation event.
Confidence in my forecast:  Low

.
Date Range:  December 8th-9th
Event:  Near normal to below normal temperatures.
Severe Risk:  Unknown
Frozen Precipitation Risk:  Possible
Details:  Potential precipitation event.
Confidence in my forecast:  Low

.
.
Remember that as a general policy, in the long range outlook, I will NOT mention severe thunderstorms more than 72 hours in advance.  I will mention thunderstorm risks and I will give as many details as possible.  The word severe will be reserved for the short range forecast.

-----------------------------  
.
1.  Basically watching the next storm system for Saturday night into next Wednesday.  Widespread showers and thunderstorms are likely to occur in our region.  Right now the severe weather risk appears minimal.  Will monitor - remember that I try to keep the severe forecast in the short range section of the blog.
.
Heavy rain will be possible - widespread 1-2" of rain with pockets of 2-4" of rain not out of the question.   I will need to fine tune the exact placement of the heaviest rain bands.
.
Here is the rainfall map from the LAST seven days - you can see that we don't need a lot more rain.

THANKSGIVING will be DRY and cool!  Enjoy that part of the forecast.
.
Another storm system will impact the region around the 25th-27th.  This could bring additional chances for showers and thunderstorms.  Locally heavy rain will again be possible with this storm.  Too soon to make a call on wintry precipitation.  There will be cold air following the storm.  Another widespread 1/2-1" of rain likely.  Pockets of heavy very well possible.
.
Here is the 500 mb map from www.wright-weather.com - showing you the strong jet diving south and pulling up moisture into our region.  This is for the storm around the 26th - give or take a day.  Will be watching this one closely, as well.  Click images for real view size.
.


.
And the 300 mb jet stream map - dive dive dive - but hey, what does that mean for our weather?  That is what you care about.  Well - it could mean a significant rain event - thunderstorms - the whole nine yards.  Wayyyyy too soon to make an actual forecast - but this is a system we have been talking about for awhile.  Active period.
.

.


There could be several inches of rain between now and the end of the month.  It would not take too much more rain to cause some hydrological problems in the region (flooding).  This will need to be monitored.  Flooding concerns would mostly be low lying areas that typically have problems during lengthy periods of rain - small streams - ditches - poor drainage areas. 

.
Check out the latest six to ten day precipitation outlook.  Above normal precipitation is forecast for our region.
.
.
November is looking as if it will be a bit of a roller coaster in the temperature department - if we do end up with several deep storm systems then we would experience warm air moving up ahead of the storms and then cold air behind the systems.  Analogs are showing a cold to very cold December into  February - with a cooler than average spring and stormy/wet spring. The cold air this winter will depend on the blocking - more blocking = colder weather.
.
Now is a GREAT time to buy a NOAA All Hazards Weather Radio.  Better to have one before storms strike than to be without one during an event.  I recommend the Midland Model 300 NOAA All Hazards Weather Radio - that is what I use here at my house!
