KEY MESSAGES

Updated at 1036 PM CDT Tue Sep 22 2026

- A mostly dry cold front moves through today, bringing a shift to northerly winds and noticeably lower humidity. Relatively quiet and dry weather continues through the week.

SHORT TERM

(Now through Saturday) Issued at 1036 PM CDT Tue Sep 22 2026

Very tranquil but warm conditions will remain through the short term. A dry frontal passage will cause dew pt temps to fall today, and at first this process will be slow and gradual on northerly winds. Then the bulk of the dry air moves in after sunset today. Eventhough high temps will remain warm, lows will fall to around room temp as 72F should dot the map in many locations each morning. The northern portion of the area will see temps a bit cooler but only getting to the upper 60s for some. This relatively cooler but drier air should remain into the weekend with some fluctuations occurring through that time frame in dew pt temps. Precip chances will be too low to really show in the fcast for the short term.

LONG TERM

(Saturday night through Tuesday) Issued at 1036 PM CDT Tue Sep 22 2026

To end the work week, we will start to see the upper level bridge retrograde a little back westward as the troughing over the east coast deepens. We will continue to see lowering dew points heading into the early part of the weekend as northeasterly flow continues to bring drier air into the region. Early morning low temperatures are noticeably a tick cooler, with most northern areas in the mid to upper 60s. Meanwhile afternoon highs will still be in the upper 80s to lower 90s through the long term forecast period as we still feel the effects of the upper ridge. Heading into the later part of the weekend, we will switch back to southeasterly flow which will bring moisture back in.

In terms of precipitation, the drier air mass that moves in towards the end of the week is shown in the PoPs which don't get above ~10% for onshore areas through Sunday. Offshore marine areas may see some isolated convection, but even that looks to be very limited. Just outside the long term period, we may start to see PoPs creep back up with the moisture recovery that starts Sunday.
