KEY MESSAGES
- Chance of light wintry precipitation Friday.
- There remains low confidence for the Sunday-Tuesday storm system with considerable spread in model guidance.
DISCUSSION
Issued at 321 AM CDT Thu Mar 28 2024
Skies are clear regionwide this morning and winds have dropped off across western Minnesota where temperatures are in the single digits and low teens. Farther east where winds are steadier, temperatures remain in the low 20s - relatively mild all things considering. Clear skies will prevail through the afternoon, as will the light winds. Highs will reach the upper 20s in western MN and low to mid 30s east.
A shortwave will track from Nevada today to North Dakota Friday with another impulse over the Mid Missouri Valley.
Precipitation will break out across central and northern MN early Friday, but should develop farther south into eastern MN and WI by evening as the two waves begin to phase. Temperatures aloft will be warm to start with the risk of any snow low.
Depending on surface temperature and timing of precipitation development, there could be a brief period of light freezing rain. Significant impacts are not expected as any amounts would be very light. All precip will turn to rain by afternoon as temperatures reach the 30s and 40s.
That passing system will lay a baroclinic zone across the central Plains to lower Great Lakes Saturday and Sunday. A longwave trough over the West Coast will slowly come onshore late this weekend and spawn an area of low pressure over the central Plains by Monday. The track of such low exhibits a lot of spread, and thus there is considerable uncertainty with how far north any precip would make it across the Upper Midwest.
Deterministic guidance would keep it all south, but several ensemble members from the GEFS and EPS are quite heavy with QPF.
PoPs remain in the ballpark of 50 percent, which is reasonable given the spread. This system looks milder than the last one and doesn't have arctic air to tap into so most precip should be in the form of rain. However, as with any spring system, there could be a stripe of snow if the band is heavy enough.
Ridging will build back to the central U.S. midweek and temperatures should return to above normal levels late in the period.
