Area forecast discussion 
National Weather Service Jackson MS 
323 PM CDT Tuesday may 22 2012 


Discussion... 
a large trough over the eastern Continental U.S. Is slowly moving north and 
east. The upper low is currently over east Alabama and the 
associated frontal boundary is stretching down to and across the 
Gulf Coast...triggering storms along it. The passing of the front 
means drier air for US. Dewpoints are in the 50s now and precipitable waters  are 
below 1 inch across our area. The leftover moisture from the frontal 
passage has formed some scattered cumulus over the southern half of the 
County Warning Area. As the sun GOES down...the skies will clear. 


Forecast is fairly straightforward for the next few days or so. 
Wednesday...temperatures will warm to above normal again /mid to upper 
80s/. A little shortwave moving over the County Warning Area could help trigger some 
isolated storms in the afternoon over the far southwest. Not very 
confident this will happen however. Thursday Onward...high pressure 
begins to build into the south. Temperatures will warm to the low to middle 
90s by the weekend. The high pressure will hold for the next week 
until a disturbance moves into the area again. /10/ 


Long term... 
Thursday through next Tuesday... with high pressure at the 
surface...upper ridging will strengthen and remain firmly in place 
across the region during much of the forecast period. Any chances for 
rain during this time will be slim and confined to the afternoon 
hours during peak heating. Conditions will also warm through the 
period as highs climb into the lower & middle 90s heading into 
Memorial Day weekend. Meanwhile...lows each night will only fall into 
the middle and upper 60s. /19/

Aviation... 
predominantly VFR conds will prevail over the next 24 hours. MVFR visibility 
restrictions may develop around sunrise at mei/hbg. Light nearly winds 
will continue through the rest of the day...gradually becmg nerly/Erly 
tomorrow morning. /Bk/
