10/8 – Rob Knight’s “Post-Cold Front” Forecast

0

The cold front that has been discussed for days has moved through the area. Local models indicate a low end chance for showers late this afternoon to our west. Our local atmosphere doesn’t support rain just low level clouds. In addition, water vapor imagery shows very dry mid-level air surging southeast across LA and MS. Meanwhile, temperatures will finally fail to break any records today with highs in the lower to mid-80s.

Wednesday should be a similar day as today albeit a bump in temps back into the upper 80s as a weak high-pressure passes overhead as a few outer coastal showers will be possible. As this high pressure slides farther east, southerly flow will gradually bring dew-points back up into the lower 70s. This, combined with above normal temps, will bring back the chance for rain. Friday into Saturday, an upper level low dropping out of the Rockies will track across the mid-Mississippi Valley to the Great Lakes. This will send a cold front through the area Saturday evening to Saturday night. Post frontal clearing should be relatively short, most likely just a day, before southerly moist air returns along with warming temps.
