After a bit of a chilly start, a warm albeit breezy afternoon has
unfolded across the area, with temperatures generally in the mid
to upper 60s, with some lower 70s across lower SE TX/SW LA.
Another cool night is on tap, with winds relaxing as SFC high
pressure to the west edges into the area. Underneath a clear sky
and amid a dry airmass, good radiational cooling is expected, and
this is forecast to be the coolest night areawide of the forecast
period, with readings from the lower/mid 40s north and mid/upper
Another pleasant afternoon expected tomorrow with SFC high
pressure continuing to drift east into the area. The high is
expected to depart to the east late tomorrow night into THU, with
ESE winds on the back side of the high starting to nudge MSTR and
warmer temperatures back into the region. Accelerated warming and
moistening is expected THU night into FRI as winds become more
southerly and strengthen a bit, while the flow aloft flattens out
as weak ridging slides overhead. Warm and humid weather will
continue through the weekend with best rain chances remaining
generally north of the area, with at least small chances returning
areawide early next week. Rain chances by mid week are more
uncertain as disparity in global models persists with the eventual
evolution of a robust WRN CONUS trof. For now, have leaned toward
the solutions which keep the heaviest rainfall well to our NW.
Strong and gusty northwest Winds will slowly subside through
tonight into Wednesday morning as high pressure settles across
the area. Southerly winds return Thursday as the high moves off to
the east with a modest onshore flow developing to end the week
and prevailing through the weekend.
