Sunday, June 5, 2011: Heat so soon? A few strong/severe storms - spotty

Sunday, June 5, 2011
 .
A few thunderstorms today - especially the northern and eastern parts of the region.  Some of these storms could produce severe weather.  See last nights discussion.  If any watches or warnings are issued then tune into NOAA Weather Radio or local media for the most up to date information.

HEADLINE:  Sunday will bring more hot temperatures - a few storms - especially over our north and east counties.   Some of the storms could produce a few reports of severe weather.  Try to stay cool!  

.
Remember that leaving children, elderly people, and pets in cars - during the summer heat - can be a deadly combination.  
.
Record high temperatures stretched across our region on Saturday.  The temperature at the Paducah, Kentucky National Weather Service reached 98 degrees.  This broke their old record high of 96 degrees set back in 1942.  Temperatures at Cairo reached 100 degrees.  Quite impressive for this early in the season.
.
Here is a map showing the extensive area of heat covering the central and eastern United States.  This is a snap shot of the apparent temperatures as of 230 pm on Saturday.

CURRENT CONDITIONS are now available on the web-site - this includes temperatures, wind speed, dew points, heat index, barometric pressure, and more!  Click here 
.
The summer forecast calls for an early start to the heat and then it will level off some - perhaps even below normal temperaturess once everything is averaged out (June through August).  I am not a huge fan of long range forecasting - but that is how it looks for now.
.
In this extreme weather cycle (that has been going on for the last decade) I am always concerned when the rain stops falling.  We certainly don't want or need another drought. 
.
Keep in mind that during this period of heat and humidity pop-up thunderstorms can occur.  The storms are not expected to be widespread and would be scattered at best.  I will mention them as a stray thunderstorm in the forecast.  Also keep in mind that any storms that manage to form could produce isolated reports of severe weather.  Rarely can one rule out a stray severe thunderstorm in this type of air mass (lot of heat and humidity = energy).  Wind fields are not overly impressive.  Normally for severe weather you would want to see strong wind fields. 
.
The Storm Prediction Center has placed our far northern and eastern counties in a slight risk for severe thunderstorms on Sunday.  This risk area is along a weak frontal boundary.  
.
Storms that do form would likely move from the northwest towards the southeast.  Best chances for storms will be along a line from St Louis to just west of Evansville and then to Murray - from there eastward.  Check radar and listen to NOAA Weather Radio in the event a few storms become severe on Sunday.

How much above normal will high temperatures be tomorrow?  Several degrees!  The map below shows you the departure from normal highs (normal highs are around 79-82 degrees).  For example if the normal high is 80 degrees and the actual high is 90 degrees then we would be 10 degrees above normal. You can find this map on the web-site, as well - click here.

The forecast for severe or extreme weather risk for today, tonight, and tomorrow... 


Sunday:  A small chance for strong/severe storms - mostly over our northern and eastern counties.  The Storm Prediction Center has placed some of our counties in a slight risk zone.  Heat index values may top 100 degrees.
.
Sunday night:  A few evening thunderstorms will be possible. 
.
Monday:  No severe weather is anticipated.  A stray thunderstorm can't be ruled out - if a storm were to form then it could produce lightning and gusty winds.  Heat index values may be above 100 degrees.
.
Monday Night:  No severe weather is anticipated.  A stray thunderstorm can't be ruled out - if a storm were to form then it could produce lightning and gusty winds.

Tuesday:  No severe weather is anticipated.  A stray thunderstorm can't be ruled out - if a storm were to form then it could produce lightning and gusty winds.  High heat index values will make it quite uncomfortable to work outside.

.
Severe weather outlook for Sunday - the orange area represents where the SPC believes a few severe storms will be possible.  Remember that the SPC updates their outlooks several times a day.  For the most up to date outlook click here.  Text for the outlook - can also be found on that same page - simply hit the day 1 discussion button.
.
The yellow area on the map indicates where thunderstorms are possible.  Thunderstorms in the yellow area are expected to remain below severe limits.
.
A slight risk for severe storms means that a few severe storms will likely occur but they should not be widespread in nature.  Remember that a severe thunderstorm by definition is a storm that produces quarter size hail - or larger and winds of at least 58 mph.  Tornadoes, of course, as well.  Also remember that lightning is a hazard for anyone outdoors.  If you can hear thunder then you should seek shelter.

There is an area of interest in the Caribbean.  The main concern is flash flooding over some of the islands.  This disturbance will move slowly north/northwest of the coming days. Some slow development is not out of the question.

Latest National Hurricane Center Tropical Outlook - click here. 
 
Speaking of the tropics - there is an interesting feature off the California coast.  This is a beautiful deep low pressure area that is so wound up that you can literally see the cyclone on satellite images.  This is not a tropical storm or hurricane - this is simply an unusually deep low pressure system off the coast.  You normally will not see a feature like this in June.  Perhaps in the winter months - but not in June.
.
This storm system is bringing copious amounts of rain to portions of California,  Even a few rainfall records were broken.

You can now view the 6-10 and 8-14 day forecasts!  Maps are available by clicking here.  
.
I have some new maps issued today by the National Weather Service.  The 6 to 10 day temperature outlook (for June 9th through June 13th) continues to indicate above normal temperatures.  Remember - this map shows you the probability of temperatures being below or above normal.  The blue would be below normal temperatures - the yellow and orange/red areas indicate above normal temperatures. 
.
.
To go along with the temperature map - let's take a look at the precipitation forecast for the 6 to 10 day period and the 8 to 14 day period.  Not the best news for farmers.  Below normal precipitation is forecast.  That does not mean it won't rain - it just means that the odds favor below normal precipitation totals.  Keep in mind that in this type of pattern it only takes one or two rounds of thunderstorms to produce locally heavy rain.  Something I will be watching for in the coming weeks as the pattern starts to shift towards a more northwest flow (we hope) - possibly bringing some squall line events (see the summer forecast from last week).
.
The green areas represent areas where precipitation is likely going to be above normal.  The yellow and orange/brown regions indicates below normal precipitation.  You can see that "ring of fire" that I mentioned in my summer forecast.  Under the high pressure ridge you have dry conditions - around the border of the ridge you normally have showers and thunderstorms.  You can see that arch in the above normal precipitation region (again around the northern and eastern part of the high pressure ridge)
.
This map is for the June 9th through June 13th time frame.
.
.
And here is the 8-14 day precipitation outlook.  Is it possible that there will be some tropical development in the Caribbean that might move northward?  It is something I will be watching in the coming days.  
.
In this outlook we are in the neutral zone.  Perhaps normal precipitation.  This would be the June 13th through June 17th time frame.
.




1.  Warm weather to continue into the upcoming week.  No big changes in the overall pattern - at least during the upcoming 5-6 day period.

2.  Perhaps some more active weather as we push towards the middle/end of this coming week.  I have been saying for awhile that the pattern might start to break down towards the middle or end of next week.  But - this is a difficult pattern to shake.  So - stay tuned.   


.
3.  Keep in mind that my summer forecast is for an early start to summer (what we are seeing right now) and then we level off some as the ridge of high pressure shifts west into the southwest United States.  That would leave us with more NW flow events - meaning our systems will move in from the St Louis region - heavy thunderstorms and squall lines.  The exact placement of this ring of fire is still in question.  But - the NW flow should bring us more season temperatures and normal to perhaps above normal precipitation - when averaged out from June through the end of August.
