Area Forecast Discussion

.DISCUSSION...
IR imagery confirming mostly clear skies across the entire Four
State Region late this evening with the exception being some very
thin cirrus across the Ouachitas of Southeast Oklahoma into
Western Arkansas. Some 5kft moisture locked in across the Lower
Miss Valley to our east but that cloud cover should stay to our
east overnight. Sfc ridge axis was located across North Central/
Northeast Louisiana late this evening and should continue to
quickly migrate to our east overnight as well. Already seeing
light southeasterly flow returning at the sfc across our western
zones and while that will allow for a little mixing...it should
not hurt temperatures falling to forecasted minimums. Overnight
Sfc RH values underneath the sfc ridge suggests that we could see
some patchy fog developing later tonight across our eastern zones.
This is already in the forecast but for the update, expanded the
patchy fog wording a little further north to encompass portions
of South Central Arkansas. Also lowered overnight min temps a
degree or two across these same areas of South Central Arkansas
into Northeast Louisiana given the expected radiational cooling
across these areas not to mention the effects of the patchy fog
with overnight lows. Otherwise...remainder of the forecast is in
pretty good shape.

Warm day on tap for Thursday areawide with increasing southerly
winds...especially across our western third where we will be
flirting with Lake Wind Advisory criteria. Update out
shortly...13.
