This forecast analysis covers far southern Illinois, southeast Missouri, southwest Indiana, western                       Kentucky, and northwest Tennessee

HEADLINES:  A complicated forecast over the coming days.  It isn't that we aren't sure whether or not it is or isn't going to rain - we know the answer to that question!  It is going to rain.  The question will be the placement of the frontal boundary and ripples of energy that move up along the frontal boundary.


Right now it appears that the heaviest rainfall amounts will be placed over southern Indiana into Kentucky and Tennessee.  Lesser rainfall totals are likely across southern Illinois and southeast Missouri.

Showers will be ongoing on Thursday night and continue into Sunday night.  There will be several distinct chances of rain.  One of those being on Friday itself - then scattered on Saturday - then another widespread chance on Sunday into Sunday evening.

There will be some thunderstorms with this system.  There will be a small risk for a few severe thunderstorms on Sunday into Sunday evening.  Large hail, damaging winds, and an isolated tornado can't be ruled out with the most intense cells.  Monitor local media and the NWS for up to the minute watches and warnings..

Rainfall totals should be in the 0.50"-1.00" over southern Illinois and southeast Missouri (from start to finish) and in the 1"-2"+ range over parts of southern Indiana down into Kentucky and Tennessee.

Rainfall forecast


There remains some questions on how numerous the showers will be on Saturday.  I know there are several parades in the region.  I believe that showers will be more scattered late on Saturday morning into early afternoon - then perhaps more numerous during the evening hours into Sunday.  There will be a better chance for precipitation over our southeast counties vs northwest (that means a better chance over parts of Indiana and Kentucky/Tennessee).

Check radars if you have outdoor plans and check the latest forecast numbers.

Radars http://weatherobservatory.com/weather-radar.htm

Our region needs this rainfall.  Drought conditions prevail over all of our counties.  We could use several inches of rain.

The rain may end as a mix of sleet and snow on Monday morning.  Right now the chance for accumulation appears small - this should be monitored.

The good news is that we are entering an active pattern of the coming weeks.  I promised you that the second and third weeks of December would become more active.  That appears to be happening - starting with this system.

It is too early to make a call as to whether any of the systems after this one could produce snow or ice.  Some of the model data is showing enough cold air for some frozen precipitation in the coming weeks.  The problems with long range data is that it doesn't always verify.  So - I will keep monitoring and updating as each event draws closer.

The next best chance for rain and storms will arrive around Friday night or Saturday - December 14th/15th time frame.  Looks like another warm system - that means rain!



Rain over the coming days could mess up outdoor plans.  There will be a chance for a few severe thunderstorms on Sunday afternoon and evening.  Monitor local media for the most up to the minute watches and/or warnings.


Rain may end as a brief mix of snow and sleet on Monday morning.



Check radars if you have outdoor plans.  Rain is likely over the coming days. 

 

Wild card in this forecast will be just how widespread the rain will be over the coming days and the exact placement of the frontal boundaries.  I know there are a lot of outdoor plans on Saturday (parades and other).  Check radars if you have concerns.


The next wild card will be whether the cold air will move in quick enough to produce a quick shot of sleet or sleet and snow on Monday morning.

What are my current thoughts on the chances for significant snow or ice over the next 7 days


A chance for a mixture of sleet and snow on Monday morning as the precipitation comes to an end.  Data is mixed on whether this will or won't happen.  Right now it appears the window of opportunity for frozen precipitation would be between 3 am on Monday morning and 11 am on Monday morning.  The main area of concern would be from the Missouri Bootheel into parts of KY/TN.


I will update the Facebook page with the latest information.

1.  Drought conditions continue over our region.  We desperately need above normal rainfall.  It does appear the next 2-3 weeks will provide some opportunity for additional rainfall.

If you are a weather enthusiast then I recommend listening to WeatherBrains each week!  For a more in-depth look at what is happening in meteorology.





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!
