.DISCUSSION...
Issued at 351 AM EDT Sun Jul 27 2025
An anomalously strong upper level ridge will dominate the
weather early this upcoming week with temperatures above to
much above normal. Energy topping the upstream ridge over
western North America will help trigger showers and scattered
thunderstorms downstream over the forecast area early this week.
Severe storms or flooding are not expected given weak winds in
the lower layers, sufficient storm movement and relatively warm
mid level temperatures.
Another heat episode is setting up for Monday and Tuesday as a
large upper level ridge extends north of the Ohio River. Have
issued a Heat Advisory for early this week for heat indices
between 100 and 110 degrees. A cold front will bring scattered
thunderstorms to the area Wednesday before somewhat cooler air
arrives late this week.

.AVIATION /12Z TAFS THROUGH 12Z MONDAY/...
Issued at 647 AM EDT Sun Jul 27 2025
Very moist environment could support some MVFR ceilings through
the next few hours before diurnal mixing increases. Convection
around KFWA should continue to wane but a second round is
possible during the afternoon. Coverage of any additional storms
should be low given increasing subsidence/capping and decreasing
instability due to warming temps aloft. Some fog is possible
around KFWA Monday morning but confidence is too low to mention
this far out.
