..update to aviation... 


Short term (today through thursday)... 


Short term focus remains on gusty winds and increasing 
temperatures over the coming days...as surface high pressure 
pushes east and strong upper level ridging develops over the 
southeastern Continental U.S.. 


An expansive area of surface ridging currently stretches from the 
Great Lakes...across the Ozarks...south toward the arklatex. This 
area of high pressure will slowly slide east of the area 
tonight...likely resulting in a rather large gradient for 
overnight lows. Temperatures over the Eastern Ozarks...where good 
radiational cooling conditions should persist...will drop into 
the upper 40s...while a persistent southeast breeze over western 
Missouri should keep temperatures from falling much below 60. 


Southerly winds will increase through the day on Wednesday...as 
the surface reflection of an amplifying upper level pattern 
results in a tightening surface pressure gradient over the region. 
This will continue through much of the day Thursday...as surface 
low pressure further organizes in the Central Plains. Winds both 
days will be quite gusty as a result...with sustained speeds 
between 20 and 25 miles per hour...and gusts of 30 to 35 miles per hour expected. A 
very warm airmass will build into the region Wednesday and 
Thursday...with middle to upper 80s common. With southerly 
winds...the warmest readings look to be across the U.S. 54 
corridor...where downslope flow from the plateau will add a 
couple of degrees to highs. 


By Thursday afternoon and evening...a cold front will try to drop 
south over central/north central Kansas and Missouri as a 
shortwave ejects east from Colorado into eastern Nebraska and 
Iowa. The airmass south and east of the front will be very 
capped...and only a small window of opportunity exists over the 
far northern reaches of the County Warning Area where ascent from the 
aforementioned shortwave may be enough to break the cap in a few 
spots. Overall...however...I think the cap will just remain too 
strong for convection...and as such...have left probability of precipitation out of the 
forecast at this time.

&& 
long term (friday through tuesday)... 


An amplifying western trough to eastern ridge pattern across the 
Continental U.S. Will dominate the extended period forecast through the 
weekend. Rain chances Friday and beyond will be minimal with the 
storm track and frontal boundary remaining just north of the 
area. Surface high pressure entrenched over the southeastern 
Continental U.S. Under the ridge aloft will sustain southerly surface flow 
off of the Gulf of Mexico through the weekend. This will result 
in temperatures well above normal in the lower to middle 90s across 
the area through the weekend. Surface moisture will also increase 
across the area. Dewpoints approaching 70 degrees can be expected 
western areas by Friday afternoon. This pattern will begin to 
break down toward the end of the weekend as the trough over the 
western Continental U.S. Begins to move toward the east. Early in the work 
week...the storm track is expected by the long range models to 
move further south and east ahead of a major shortwave trough 
passing over the northern tier of states. This may push a frontal 
boundary into the area Monday into Tuesday.

Aviation... 


For the 00z...VFR will prevail with high pressure in control of 
the weather pattern over the Ozarks. Light southerly winds will 
become gusty by middle morning tomorrow and through the afternoon on 
Wednesday. Mostly clear skies will be the rule of thumb through tomorrow.

Climate... 


A period of very warm temperatures appears to be in store as we head 
into the Memorial Day weekend. Here are the record highs and record 
warm low temperatures from Wednesday through the Holiday weekend for 
Springfield...Joplin...West Plains...and Vichy/Rolla.
