DISCUSSION

- Showers Early this Morning; Marginal Severe Risk Expanded
Showers out ahead of the incoming short wave will continue to spread over the region early this morning. The dry air at the surface delayed the onset of precipitation, however scattered showers continue to spread over the region and will continue through the first half of the morning. Coinciding with this short wave will be a strong low level jet. Winds upwards of 35 mph will be possible through the early morning hours. The 925 mb winds should become more amplified with more directional shear from the 850 and 700 mb layers. Looking at BUFKIT soundings CAMS have a weak capping inversion from 2,500 to 4KFT this afternoon. If this is breached, the steep low to mid level lapse rates of 7 to 9 C/KM should greatly aid in convection.
Couple those lapse rates, the strong shear from the LLJ and the cold air aloft and there is a decent chance for severe hail.
Latest mesoscale analysis has decent DCAPE moving into the region.
Given that, SPC has expanded the marginal risk for severe storms for across the region this afternoon. Timing wise, latest CAMS brings the best opportunity for strongest convection will be late in the day associated with the cold front, around 00Z. A secondary LLJ is associated with that boundary as well, though it is weaker then the one moving through this morning.
- Frost/Freeze Risk Wednesday Night/Thursday Morning
Clearing skies under surface high pressure and very dry air at the lower levels will create favorable conditions for radiational cooling Wednesday night into Thursday morning. Temperatures will likely drop into the upper 20s across a wide swath of southern Lower Michigan. The coldest temperatures will probably in the northeast counties where mid 20s can't be ruled out. The good news is that the trend of a slightly warmer airmass at 850 mb continues with recent model runs.
- Warmer and unsettled weather moves in for the weekend
As this final blast of cold air departs the area, a reorientation of the longwave pattern will move into the central CONUS, setting Michigan up initially on the "sunny" side of a building upper ridge, but by Friday afternoon the ridge axis will have passed us and we'll fall into several days of deep southwesterly flow.
This pattern will allow much warmer and more humid air to stream into our state, along with fairly plentiful cloudiness. At least 2 major disturbances/shortwaves will move through this southwest flow, and bring rounds of rain and possibly storms beginning Friday night and continuing all weekend. It's unlikely the whole weekend will be a washout, but the exact timing and placement of these shortwaves are still pretty uncertain at this time, so some of the more pertinent forecast details remain elusive. Instability and the risk of possible severe weather will be monitored over the coming days, as breaks of sunshine during the day followed by one of these shortwaves coming through near peak heating could easily result in a severe threat.
AVIATION /18Z TAFS THROUGH 18Z WEDNESDAY/
Issued at 124 PM EDT Tue Apr 23 2024
VFR conditions will continue this afternoon then an increasing chances of showers and some scattered thunderstorms will bring areas of MVFR around 00Z. THe thunderstorms could have localized hail and high winds but the threat is low and coverage is isolated. Ceilings around 1500 to 200 feet AGL is expected overnight with some slow clearing in Wednesday morning.
Southwest wilds will gust to near 30 knots at times this afternoon. Winds will go northwest tonight and north by Wednesday morning with some gusts over 20 knots.
MARINE
Issued at 403 AM EDT Tue Apr 23 2024
An active/hazardous period on Lake Michigan will continue through Wednesday. Gusty winds will continue with southerly flow this morning. Winds will briefly slacken over the lake this afternoon.
However winds will shift to the north to 30 kts behind the front tonight into Wednesday. Though the small craft remains, there is still a chance for brief periods of gales. Hazardous winds and waves should subside Wednesday night into Thursday as a sfc ridge builds overhead.
