KEY MESSAGES
- Isolated to scattered strong to severe storms in the Arrowhead and northwest Wisconsin this afternoon. Hail up to 1.5" in diameter and wind gusts to 60 mph possible.
- Short dry spell Saturday night and Sunday morning before our active weather pattern returns next week with multiple periods of rain through the week.
DISCUSSION
Issued at 348 PM CDT Sat May 18 2024
We're still expecting a threat for severe weather through about 7 PM this afternoon. Current observations out ahead of the cold front in northwest Wisconsin are pretty warm and moist; temperatures hovering near 80 degrees and dew points in the 50s to low 60s. One caveat has been some fairly robust stratocumulus coverage, but this is starting to erode over Douglas/Burnett/Washburn counties. We're starting to see a couple cells pop up along the lake breeze boundary over in Bayfield/Ashland counties. In the Arrowhead, conditions are cooler but nonetheless instability is building out ahead of the front. Around or slightly above 1000 J/kg of SBCAPE is out there, and we're looking at favorable 0-6km wind shear from 40-50 kt as well. It is now a waiting game for the cap to bust everywhere, and once it does, storms should fire pretty quickly. We will be looking at a pretty short window where strong to severe storms will be possible until about 7 PM when the cold front clears the region. Until then, discrete cells will largely be favored, which will keep large hail as the primary threat (up to around 1.5" in diameter, though it wouldn't be surprising to get a report or two a little larger than that). Could see wind gusts to 60 mph as well, and perhaps 70 mph which would be more likely (if it happens at all) further east (Iron/Price counties) where storms may start to consolidate. The risk for tornadoes remains very low, but a brief spinup couldn't be ruled out, again mainly in Iron/Price counties.
As the cold front passes through by around 7 PM, the storm threat is expected to quickly diminish, leading to a quiet night. On Sunday, another low pressure system will approach from the southwest and bring more rain to the region as early as Sunday afternoon. This will mainly be a synoptically-forced rain, but a few embedded rumbles of thunder can't be ruled out.
This will be a fairly quick-moving system ending on Monday, so heavy rain amounts are not expected. Totals generally around or less than an inch with heavier amounts more likely in northwest Wisconsin.
Another potentially larger system is looking likely to make its way into the region Tuesday into Wednesday, and model ensembles with this one suggest some pretty hefty rainfall amounts may be possible. We could be looking at fairly widespread totals around an inch or two, and perhaps locally higher. This will be another situation where, right now, the convective threat appears low, but the main threat will be localized minor flooding with some of these higher rainfall amounts. Depending on the storm track, rainfall amounts and convective potential could go up or down from where they're at now. The active pattern looks to continue through the end of the week with more rain chances.
AVIATION /06Z TAFS THROUGH 06Z MONDAY/
Issued at 1244 AM CDT Sun May 19 2024
VFR conditions are expected this TAF period. southwest winds of less than 10 kts overnight will pick up to 10-15 kts in the 15z-21z time frame Sunday, then decrease again after 22z. A low pressure system will push high clouds into the area from the west on Sunday, with cloud bases slowly lowering through the day. Showers will begin to affect the terminals around 00z, but conditions will remain VFR.
MARINE /FOR NEAR SHORE WATERS OF WESTERN LAKE SUPERIOR/
Issued at 348 PM CDT Sat May 18 2024
Winds are expected to shift to west to southwesterly this afternoon as a cold front passes through, and gusty winds from 20 to 25 knots are expected around the head of the lake through this early evening as that happens. Another threat will be isolated to scattered storms that could be strong to severe through about 7 PM with large hail to 1.5" in diameter and wind gusts to around 50 kt possible. Winds become lighter through Sunday and Sunday night following the cold front. Wind direction will become northeasterly again ahead of low pressure going into Monday.
