.SHORT TERM...
(This afternoon through Wednesday)
Issued at 254 PM EST Tue Dec 20 2022
An upper disturbance will continue to move east in the
flow this
evening and finally offshore overnight. The
zonal flow aloft will
continue through the day tomorrow, but begin to shift to the SW
tomorrow night. At the surface, a weak low pressure wave off the
NE FL coast will
meander off the SE coast while a
ridge axis
remains situated from the Mid Atlantic states down the spine of
the Appalachians (a wedge).
The precipitation associated with the
shortwave should taper off from
west to east this evening for most locales. A brief dry period is
anticipated Wednesday, although we will continue to be wedged.
Precip on the backside of the low off the SE coast should begin to
spread onshore and into the wedge tomorrow evening/overnight.
Right
now, temps look to remain in the middle to upper 30s, but the models
may not be handling dewpoints upstream in the wedge very well -
especially at precip onset. The weak low pressure offshore may end
up reinforcing the wedge and bringing those mid/upper 20s dews
further SW. Will have to watch P-Type closely.
Have bumped MaxT`s down a degree or two within the wedge tomorrow.
