Short term /today through Saturday/...

High pressure ridge continues across the region keeping a quiet
forecast in the short term. Winds expected to stay mainly our of the
east at 10mph or less with mostly clear skies today. Will see
increasing clouds over the state Saturday as the over all flow
becomes more southerly but still no precipitation expected. High
temps today and Saturday will stay mainly in the 70s and lower 80s
will low temps tonight in the 40s and 50s.

Long term /Saturday night through Thursday/...

Once again, no significant changes to the long-term forecast trends
with this forecast cycle. Medium-range models are beginning to
converge on the timing/strength/path of the fairly vigorous system
impacting the region early next week. Best chances for widespread,
heavier, rain, and some potential for at least isolated strong to
severe thunderstorms, continues to center around the Monday
timeframe. Behind this system and a secondary strong shot of cold
advection associated with another strong short wave, significantly
below normal temperatures appear to be in store for region for the
latter half of the week.

Severe thunderstorm potential for the early week system continues to
be somewhat uncertain. Models currently are not bringing much
instability into the region associated with this system. However,
with a very strong, dynamic system and good shear, the potential for
damaging thunderstorm wind gusts, and even an isolated tornado,
cannot be ruled out.
