.Short Term.../through Friday/...

Surface high pressure ridge will stretch across region from center 
to the southeast through Thursday. This surface high will build more
toward the east northeast Friday. In addition to being under the 
surface ridge, the region will also be under a 500mb high through 
Wednesday night as well. 

With ridging at the surface and aloft, dry weather and mainly clear 
skies to continue through Wednesday night. Once the upper ridge 
shifts to the east Thursday, upper energy will move into region.
This energy, coupled with diurnal heating could produce a few 
showers/storms over inland counties Thursday afternoon and night. 

With the surface ridge moving further away Friday, and stronger 
upper energy moving through, anticipate an increase in convective 
coverage, especially in the afternoon due to addition of diurnal 
heating. A few strong to severe storms will be possible.

Temperatures will trend above normal this period. The east coast sea
breeze will push inland each afternoon, but its push will be limited
by southwest flow.

.Long Term.../Friday night through Tuesday/...

Surface high pressure will remain to the east through Saturday, as a
cold front approaches from the west. A prefrontal trough is expected
to pass through Saturday afternoon. The cold front itself is 
expected to be stalled to the northwest of forecast area Saturday 
night, then move southeast across area Sunday into Sunday night. The
region will be in the base of an upper trough through Sunday night, 
with waves moving east through the flow. Weak surface ridging will 
build Sunday night into Monday, with another cold front affecting 
the area Tuesday. 

Precipitation chances will be greatest Friday night through Saturday
across inland counties closer to the frontal zone, while coverage
chances will be more uniform Saturday night and Sunday.

The potential will exist for strong to severe storms over the 
weekend. 

Temperatures will continue above normal this period.
