Area forecast discussion

Discussion... 


Models are holding true to the on-going midsouth forecast for the 
next five days...with high pressure throughout the column 
dominating. The only exception will be two weak impulses moving 
through the ridge that may trigger an isolated shower or storm 
both tomorrow and Memorial Day. Again the northern and western 
counties will be most at risk for this stray convection. Otherwise 
temperatures will increase...as well as a slow rise in the 
humidity starting tonight. Skies will be mostly clear to partly 
cloudy for the most part. 


The Mississippi Valley ridge will slide to the Appalachians/middle 
Atlantic coast and build further starting Tuesday. Believe the 
area will be free of precipitation with the edge of the ring of 
fire staying just off to our west across western Arkansas through 
Friday. Temperatures will run around five degrees above normal 
through the period. 


Later in the week...the GFS and Euro agree that an approaching 
cold front will impact the region for the first weekend in 
June... though the GFS is still running about 24 hours faster. 
Model disagreement though is evident in how the associated 
shortwave will push the area. For certain favorable instability 
will be in place so a risk for some severe weather will exist...as 
well as a localized heavy rain/flooding threat from storms.

VFR ceilings and visibilities will prevail through the next 24 hours. High 
level cloudiness will continue to stream over the region. 
Weakening southeast winds today will switch around to light 
southwesterly by Sunday morning.
