Warming into Tuesday. - Spotty light rain chances (25-40%) Wednesday-Thursday. && .DISCUSSION... Issued at 244 PM CDT Mon Apr 7 2025 Quiet conditions this afternoon behind a boundary with good cold advection limiting highs despite full sunshine. The brisk north winds die off quickly this evening as pressure gradient relaxes with light and variable winds overnight. The light winds, clear skies and dry airmass are expected to allow temperatures to fall quickly with lows falling into the low to mid 20s in most areas. Warm advection kicks in on Tuesday with strengthening south surface winds and a nearly 10 degree rebound in highs. Continued isentropic lift through the day into the evening will eventually lead to increasing clouds. Any precipitation is initially fighting dry near surface air into Tuesday night with saturation deepening across the south and east overnight. Some light isolated showers are possible after midnight across the south and east but with light amounts as moisture remains limited. Another shortwave approaches the state from the northwest late Wednesday night into Thursday morning with additional forcing. Scattered showers are expected once again late Wednesday night into Thursday across central Iowa with this wave. Moisture remains limited with precipitation staying scattered and light. Quiet weather returns on Friday and into Saturday with warm advection intensifying. The next shortwave passes through the Midwest on Sunday/early Monday timeframe but once again, the bulk of forcing and moisture are not across Iowa with any chances for precipitation staying limited. && .AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
