A few thunderstorms will be possible over the coming days.  A frontal boundary will find itself placed near our region.  Lightning and brief heavy rain are the main concern - an outside chance for a hail or high wind report.

If you have outdoor events then monitor radars - there could be some lighting strikes in the region.

HEADLINES:  
GOOOD Wednesday afternoon!  Hope everyone is able to enjoy these 80 degree temperatures.  It is more like May than late March - the warm weather continues.
.
Here are the 1 pm Wednesday temperatures - WARM is the word!
.
.
A cold front is draped over our region this afternoon - it will slowly move southward over the next 24 hours.  There will be a few showers and thunderstorms along this frontal boundary.  The threat for severe weather appears minimal.  Hail or a gusty wind would be the main concern - along with lightning, of course.  Weather Radars - click here
.
You can see the front on the visible satellite imagery - the band of white clouds (cumulus clouds) along and ahead of the cold front.  (This image was taken at 1 pm and shows clouds)
.

.
The official Storm Prediction Center outlook for Wednesday evening - the orange area represents a slight risk for severe storms - the yellow area is where general thunderstorms may occur. 
.


.
It appears there will be a few scattered showers and thunderstorms into Friday night.  The good news is that Saturday and Sunday may end up dry.  At once time Saturday looked like a bigger rain event.  I will continue to monitor and update - but right now it appears the weekend might be dry.
.
A bigger thunderstorm threat may materialize on Monday.  Read the extended part of the blog forecast for information on that system.
.
Here are the temperatures forecasts for Thursday and Friday - ABOVE normal will be the rule.
.
And once again CHECK OUT THESE DEPARTURES!  How much ABOVE normal will temperatures be over the next 2 days?  Quite a bit.  The pattern continues to produce warm weather - very unusual.

Remember that as a general policy, in the long range outlook, I try not to mention severe thunderstorms more than 72 hours in advance (unless the signal is so overwhelmingly convincing that it warrants a mention).  I will mention thunderstorm risks and I will give as many details as possible.  Also remember you can view the long range severe weather outlooks by visiting the Storm Prediction Center's web-site - click here

-----------------------------  

.
1.  The concern for the medium range part of the forecast will center around Monday into Tuesday.  A strong storm system is depicted by the numerical weather models to move into the central U.S. and the Ohio Valley - most likely on Monday into Tuesday.
.
This system appears to be of substantial strength - wind fields will be strong.  The one item lacking may be deep moisture return from the Gulf of Mexico.  However, there may be enough instability and moisture to spark a squall line across our region - in or near our region.  This will need to be closely monitored.
.
Right now the timing appears to be Monday afternoon into Tuesday morning - still several days away.  Fine tuning of the forecast will be necessary.
.
A risk zone for severe thunderstorms is almost certain to be outlined across portions of the region for Monday into Tuesday.  Stay tuned for updates on this system.  
.
Here are a couple of maps from the GFS off of www.wright-weather.com - my favorite source for model data.
.
This is the GFS surface map for 7 am Monday - you can see the deep storm system winding up over the central United States - the purple and pink areas are precipitation.  
.

This is the 6-7 PM map for Monday night - strong cold front moving through our region with heavy thunderstorms.
.
The GFS shows a strongly negative tilt to the 500 mb maps - this is a concern.
.

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!
