Issued at 215 AM EDT Sun Apr 6 2025 Upper low over the TX panhandle will shear quickly newd near term in response to nrn stream trough digging swd through the nrn lakes. Will keep with a low token pop mention far southeast otherwise dry elsewhere as ridging builds in. While this sys remains moisture starved, brief but decent forcing should promote a few showers north and east Monday. Much more vigorous wave follows off the nepac early Tue and into the wrn lakes Wed where it wraps up with rain likely through Thu. Combo of both systems makes for a chilly period Mon-Wed before breaking warmer next weekend. && .AVIATION /18Z TAFS THROUGH 18Z MONDAY/... Issued at 110 PM EDT Sun Apr 6 2025 A quiet night is ahead as high pressure builds in across the Midwest. Winds are coming from the northeast right now but will become light and variable overnight. On visible satellite imagery, clouds continue to move northeast across the area, with mostly clear skies expected after 00Z tonight. With light winds and clear skies overnight, some patchy fog could develop, especially since the ground is still saturated from recent rainfall. Have opted to keep fog out of the TAFs for now given that the NBM probabilities of MVFR visibilites are 10% or less overnight but will continue to monitor trends this evening. && .IWX WATCHES/WARNINGS/ADVISORIES...
