a cold front will continue to push through the coastal waters today. Northerly winds will strengthen behind the front to 15 to 25 knots and then continue into Monday. By Monday night, high pressure moving over the waters will allow the winds to relax back to 10 to 15 knots and also shift winds to the northeast and eventually southeast.

New AVIATION

SHORT TERM
(This evening through Monday night)
Issued at 229 PM CDT Sun Apr 21 2024

The axis of the shortwave that finally pushed yesterdays' cold front through the CWA is just west of the Mississippi River and will be reaching the Appalachian Mountains by sunrise Monday. The rain is done and mostly sunny skies expected for all land areas before sunset. Post frontal high pressure will usher in cooler and drier air through Monday. Cold air advection combined with cratering dewpoints will allow for lows tonight over 20 degrees colder than just a couple days ago. The highs, however, should actually be slightly warmer than today. That's a combination of very progressive nature of the upper trough and surface ridge as well as the fact that its late April which yields much more insolation compared to a couple months ago.



LONG TERM
(Tuesday through Saturday night)
Issued at 229 PM CDT Sun Apr 21 2024

Global models in good agreement that the local area will be under either zonal flow or upper level ridging this week. That'll support moderating conditions with quickly returning to above normal temps Tuesday onward. Precip forecast still looking dry with no rain chances through at least Thursday. Beyond that, model solutions diverge on when the next front/rain chances expected.



AVIATION
(00Z TAFS)
Issued at 621 PM CDT Sun Apr 21 2024

Strong northerly winds are expected to stay around after yesterday's frontal passage, with winds especially strong at NEW due to the proximity of the Lake to the north. As the trailing surface high behind the front moves over our area, winds will back down during the afternoon tomorrow.

MARINE
Issued at 229 PM CDT Sun Apr 21 2024

Cold front that started moving through the coastal waters is steadily marching south through the offshore waters. Based on the current location of the boundary, went ahead an started the Small Craft Advisory even though not all locations are seeing those 20kt winds just yet. As the sun sets, should see that typical nocturnal uptick in winds to solidify the advisory.

The progressive pattern of the upper trough and post frontal surface ridge will result in the local pressure gradient weakening rather quickly on Monday. Therefore, should see a fairly sharp drop off in wind speeds 15Z onward. Then, by Tuesday, already looking at the return of onshore flow as the ridge slides east. It should remain there this week and continue to support southeasterly flow.
