.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 200 PM EDT Saturday: Models are in good agreement on another
shortwave trough riding into and sharpening the large upper trough
over the Southeast Wednesday, inducing another sfc wave along a
persistent stationary front along the Gulf Coast or the Coastal
Plain. A sfc ridge will push in from the north and could shunt
the deeper moisture to the south and east of the area. As such,
PoPs trend down Wednesday thru Friday. The upper longwave trough
does gradually weaken/flatten out, but not completely thru next
Saturday. The flattening flow may allow the stationary coastal
front to lift back north into the area an increase our rain
chances. Despite the slightly drier trend in the models, PoPs remain
above climo in the fcst for now thru the entire medium range. Max
temps will be 5-10 deg below normal, trending toward normal by
next Saturday. Min temps will be near to slightly below normal.
