weak surface high pressure over the area to start the extended
forecast. An upper level deep long wave trough also moves in over
the region in the short term and settles in through the end of the
week. This trough pulls in some drier air and lower dew points and
cooler temperatures through Thursday. By Thursday moisture begins to increase
again across western and southern portion of our County Warning Area with
a few waves moving across the area and a frontal system moving in by
Sunday. Will continue with diurnally driven slight to low chance
probability of precipitation in across the area through days 6 and 7. Temperatures begin to
rebound Thursday and look to get back to near normal values by the
weekend.
