As high pressure continues to influence the area from the north,
dry weather will continue overnight throughout the Tennessee
Valley. Low temperatures are forecast to drop into the low to mid
60s under mostly clear skies. Due to lack of moisture, widespread
patchy fog is not anticipated. However, a very low chance of
patchy fog exists along large bodies of water.

Dry weather is forecast to persist through the afternoon on
Friday, however, CAMs are hinting at a low chance of a few
showers/thunderstorms making their way into northwest AL Friday
evening as an upper level shortwave dips into the lower
Mississippi Valley. Instability looks limited with unimpressive
shear, but steep low level lapse rates will allow a threat of
frequent lightning and gusty winds up to 40 mph if these storms
materialize. Otherwise, mostly dry conditions will continue
through the weekend with heat being the primary concern. Highs are
forecast to reach the upper 80s to mid 90s, which is ~5-10 degrees
above normal. If you have outdoor plans this weekend, be sure to
stay hydrated and take frequent breaks indoors/in the shade.

(Saturday night through Wednesday)

The longer term was suggesting that mean troughing should become
established across the eastern half of the North American domain.
In this pattern, the stronger dynamics and surface frontal
boundaries will remain well to our north and west. Thus dry and
unseasonably warm conditions should continue as we go into the
next week. But as upper level systems begin to move closer, rain
chances will return during portions of the new work week.
Low temperatures Saturday night again will be in the 60s. Highs
temperatures Sunday (the last full day of summer) will feature
highs from the mid 80s east to lower 90s west. Previously noted
upper support should arrive and bring lower end rain chances on
Monday. Monday which also the first day of Autumn (which begins
around 119 PM). More unsettled weather is expected next Tue/Wed
with low, daily chances of showers and thunderstorms mainly in the
afternoon to early evening. Low temperatures should range in the
60s, and highs from the lower 80s east to upper 80s east.
