KEY MESSAGES
1) An active weather pattern continues with episodic showers and thunderstorms beginning Wednesday afternoon, lasting through the foreseeable future. Near normal temperatures are expected to be found for daytime highs, with overnight lows being above normal.
DISCUSSION
KEY MESSAGE 1)
A weak s/w passing through srn CWA Wed afternoon will combine with daytime heating to bring a chance of showers to the se half of the CWA into Wed evening. S/w energy ahead of the next upper trough will push east and into the CWA Thurs night, bringing the next chance of activity. The trough broadens as its parent circulation tracks northeast on Friday, but lingers over the region through about Sunday. This scenario makes it necessary to keep some shower activity in the CWA during this time.
Given the expected increase in cloud cover during the day and increased moisture overnight, highs are progged to be near normal, and lows above normal through the forecast period.
AVIATION /12Z MONDAY THROUGH FRIDAY/
A few hours of MVFR cigs will develop after daybreak and then scatter out in the early afternoon, favoring clear skies by nightfall. North winds will increase to around 10kt today, then turn more northeast tonight as they decrease to 5kt or less.
OUTLOOK...Thunderstorms and MVFR to IFR conditions are possible Wednesday through Friday.
ILN WATCHES/WARNINGS/ADVISORIES
