KEY MESSAGES
- Dry overnight until Thursday afternoon
- Rain Thursday night with some thunder possible
- Cool and dry this weekend, blustery Saturday
- A bit milder early next week
UPDATE
Issued at 1019 PM EDT Wed Apr 17 2024
The forecast is largely on track this evening. A few wraparound rain showers clipped our northern areas earlier this evening, but the rest of the night should be dry as post-frontal westerly winds slowly diminish toward morning. There may be a brief window around sunrise where we see some breaks of sunshine before mid and high clouds associated with the next wave overtake our part of the world by mid/late morning. Overall Friday will be dry but fairly cloudy.
DISCUSSION
Issued at 248 PM EDT Wed Apr 17 2024
- Dry overnight until Thursday afternoon
No changes to previous thinking here. After thunderstorms clear the area later today, there could be some wraparound precipitation across our northern zones lasting into early tonight. Otherwise, we should be dry the rest of the night into Thursday afternoon, when a shower or two may be possible.
- Rain Thursday night with some thunder possible
The next possibility for rain will be associated with a very stretched out cold front extending southwestward across the central CONUS. We are in the exit region of a powerful upper jet during this time with a lot of forced ascent potential. Indeed, HRRR/SREF guidance both advertise a chance for thunder across our southern zones. This activity should exit by sunrise Friday morning.
- Cool and dry this weekend, blustery Saturday
Fair weather will return Friday through the weekend. It will become much cooler as h8 temps fall to -7 to -9 C by Saturday. Highs in the 50s Friday will decrease to the 40s Saturday - and Saturday will feel quite raw as strong gusty winds drop wind chills into the 30s. Lows could fall to near or below freezing across portions of our area early Sunday and Monday mornings as surface ridging builds in.
- A bit milder early next week
Temps will moderate a bit early next week back to near normal for this time of year. Fair weather will continue Monday. A weak low pressure system will bring a chance of rain showers Monday night into Tuesday.
Fair weather will return for the mid to latter portion of next week as another surface high pressure ridge builds in.
AVIATION /00Z TAFS THROUGH 00Z FRIDAY/
Issued at 808 PM EDT Wed Apr 17 2024
Light showers linger with overcast skies and gusty winds. The gusty winds will persist through most of the overnight period through the rain will cease by mid evening. Due to the recent heavy rainfall and cold moist air behind the front expect lowering cigs overnight with periods of IFR possible between 10Z and 13Z, especially at JXN. Otherwise expect MVFR cigs to dominate the period with improving conditions after 15Z.
MARINE
Issued at 1019 PM EDT Wed Apr 17 2024
Hazardous winds and waves will begin to improve/diminish overnight as the pressure gradient slackens. A 6AM end time for the small craft advisory still looks on track.
