KEY MESSAGES
- Noticeably less humid air prevails early this week, with below normal morning low temperatures.
- Temperatures and humidity will increase Wednesday and Thursday ahead of the next cold front, leading to a potential for a few storms.
UPDATE
Issued at 715 PM EDT MON AUG 24 2026
Made only minor adjustments for valley temperatures dropping off quickly this evening.
LONG TERM
(Wednesday through Monday) Issued at 357 PM EDT MON AUG 24 2026
Thankfully the extended portion of the forecast seems to be fairly tame. The only chances for rain will come towards the beginning of the forecast period starting Wednesday night, peaking on Thursday, and winding down again Thursday night. This will be the result of a passing weak cold front, which is set to move though the CWA during the day Thursday. However, don't expect widespread coverage of precipitation, or even a real impact on the temperature. Severe potential is also quite low without strong forcing, though still could see some rumbles of thunder. An upper level troughing pattern will be in place aloft, but our position within the trough will be that of NW flow, transporting cooler and drier air aloft into the region from Canada. Besides the passing cold front, the remainder of the time, high pressure should dominate at the surface. The result will be generally pleasant weather, with highs in the mid 80s and lows in the mid 60s. Things do warm up a bit towards the end of the period, with upper 80s and lower 90s currently forecast, as the surface high pressure begins to shift east allowing for return southerly flow and WAA to take hold.
AVIATION
(For the 00Z TAFS through 00Z Tuesday evening) ISSUED AT 715 PM EDT MON AUG 24 2026
Fog will affect most of the deeper valleys overnight and early Tuesday morning, resulting in localized IFR or worse conditions. At this point, the only TAF site forecast to potentially be affected is KSME, based on MOS guidance and last night's impacts. Otherwise, VFR conditions will prevail through the period.
JKL WATCHES/WARNINGS/ADVISORIES
