beausanalysis

An explanation of what is happening in the atmosphere over the coming days.

An area of low pressure will push into the Great Lakes and Ohio Valley today.  This low pressure area will slide east/southeast over the coming 12-24 hours.  Clouds and winds will increase over our region in response to this system.  The good news is that we are not expecting any additional significant rainfall.  There could be a few sprinkles over our northeast counties.  Nothing major.

Winds will be gusty today as the isobars tighter up.  Isobars are equal lines of pressure.  When they tighter up we usually see an increase in winds.  Low pressure over the Great Lakes and high pressure moving into the Missouri Valley will cause the isobars to tighter up.

Here is the weather map for later today.  See those blue lines?  Those are isobars (equal lines of barometric pressure).  They are tightly packed over Missouri and Illinois.  Thus, winds will increase.

No major changes in the ongoing forecast.

 

whatamiconcered

No major concerns with this forecast package.  Some gusty winds today.  Winds may gust in the 20-25 mph range.

 

wildcard

The Wild Card gives you an idea of what might change that would cause the forecast to bust. A busted forecast means a forecast that does not verify. For example, if a winter storm (the area of low pressure) shifts its track 50 miles further south than expected, then that could cause a dramatic change in how much snow might or might not accumulate.

Wild card in this forecast- cloud cover today into Friday.  It appears there will be more clouds over our eastern counties than western counties.  Somewhere along and east of a line from Mt Vernon, Illinois down towards Metropolis, Illinois and then towards Murray, Kentucky should experience a few more clouds than say southeast Missouri.

 

severeoutlook

Can we expect severe thunderstorms over the next 24 to 48 hours?  Remember that a severe thunderstorm is defined as a thunderstorm that produces 58 mph winds or higher, quarter size hail or larger, and/or a tornado.

Severe weather is not going to be a concern through Sunday.

Thunderstorm threat level is zero.

We have regional radars and local city radars – if a radar does not seem to be updating then try another one. Occasional browsers need their cache cleared. You may also try restarting your browser. That usually fixes the problem. Occasionally we do have a radar go down. That is why I have duplicates. Thus, if one fails then try another one.

If you have any problems then please send me an email beaudodson@usawx.com

We also have a new national interactive radar – you can view that radar by clicking here.

Local interactive city radars include St Louis, Mt Vernon, Evansville, Poplar Bluff, Cape Girardeau, Marion, Paducah, Hopkinsville, Memphis, Nashville, Dyersburg, and all of eastern Kentucky – these are interactive radars. Local city radars – click here

winterstorm

No winter weather concerns.  The coldest air of the season appears possible next week.  Whether or not precipitation will be associated with the cold blast has yet to be determined.

extended

The big story over the coming 2 weeks will be the cold air moving into the eastern half of the United States.  Some of the data indicates WELL below normal temperatures for much of our region.  Several cold waves will impact the region over the coming 10 day period.

This map is for next Wednesday _November 12th)

gfs_t2m_anomf_east_292

The strongest cold shot will likely occur towards the middle and end of next week.  Some data indicates temperatures could fall into the lower 20’s and upper teens over some of our counties.  That would be quite early for temperatures that low.  Still a long way off and time for changes and adjustments.

Here are some interesting maps illustrating the cold shots that are forecast to occur.

Here is the GFS model forecast for high and low temperatures centered on Paducah, Kentucky.  Note that it is indicating temperatures may not get out of the 40’s during the middle and end of next week.  Overnight lows on the GFS are down into the 20’s.

The blue lines represent the high temperatures.  The green lines represent the low temperatures.  The dates can be viewed at the bottom of the graphic.

Again, this is in the long range.  Subject to changes.

Temperature map for next Tuesday afternoon.  Check out how far south the cold air is going to spread.  Impressive for an early season cold outbreak.

Temperature map for next Wednesday afternoon.  Again, see how far south this cold air is forecast to spread.

Temperature map for next Thursday afternoon.  Brrrr

thursdayafternoon

The latest 6-10 temperature outlook shows that probabilities favor below normal temperatures.  The colors represent the % chance for above or below normal temperatures.  The dark blue indicates a 50%-70% chance that temperatures will be below normal.

8-14 Day Temperature Outlook – again it appears below normal temperatures will continue for awhile.  This map is through November 18th.
