Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
608 AM CDT Sun Apr 9 2023
.SHORT TERM… Issued at 246 AM CDT Sun Apr 9 2023
Through Monday…
Benign and mild weather will continue through Monday. Only forecast “challenge” is extent and opaqueness of cirrus and its potential minor impact on temps.
Slowly dampening shortwave trough is moving east across the northern and central Plains early this morning with plenty of cirrus evident on IR imagery in advance and this wave. There are some fairly cold cloud tops (AOB -25C) likely suggesting that the cirrus isn`t terribly thin. Given forecast soundings showing a fairly deep moist layer (AOA 20kft) and the upstream satellite trends, have nudged sky cover up a bit in the grids today. Also knocked a degree or two off of going high temps as a nod to the expected high cloudiness. What`s left of the trough should move east of the area Monday, with decreasing mid-high cloudiness expected in its wake during the day Monday.
A bit stronger southerly synoptic gradient today, so lake breeze is expected to struggle to penetrate very far inland today. Lake breeze should be most successful in moving inland along the IL north shore. By Monday, southwest winds may keep the lake breeze offshore, so progressively less lake cooling is expected today and tomorrow.
