SYNOPSIS. Issued at 242 PM EST Fri Mar 5 2021
- High Pressure and Fair Weather This Weekend
- Wet Weather Mid-Late Week as Low Pressure Moves Through
DISCUSSION. (This evening through next Friday) Issued at 242 PM EST Fri Mar 5 2021
- High Pressure and Fair Weather This Weekend
The tranquil weather of the past few days continues through the weekend as surface ridging holds sway. The high moves east early next week setting up a return flow of warmer air and increasing moisture, although any rain should hold off until Tuesday night or Wednesday.
- Wet Weather Mid-Late Week as Low Pressure Moves Through
We continue to watch for the potential of a period of heavy rain Thursday into Friday as low pressure tracks east of Lower Michigan and pushes a front through. The confidence in the details of the event are low, but there is fairly high confidence that the front will stall somewhere from southern Lower Michigan into the Ohio Valley and become the focus for a period of heavy rain.
The upper end of the QPF forecasts Wednesday through Friday from individual ensemble members is greater than 2 inches. The most likely place for this would be across the Kalamazoo River basin, which would bring some minor flooding to areas along the river. Fortunately, snow melt there is not an issue as it is further north. We will probably see some significant rises in the Muskegon and Pere Marquette River basins from snowmelt plus an estimated half inch of liquid QPF there.
There is a trend with the 12Z guidance from the ECMWF, GFS and GEM for the front to stall further south, which would shift the heavy rain threat out of Lower Michigan. In fact, the ECMWF is far enough south that a wave of low pressure forming along the front would only bring light QPF to the southern and central forecast area on Friday, and enough cold air may be in place by that time for the precip to be frozen.
AVIATION. (For the 00Z TAFS through 00Z Saturday evening) Issued at 631 PM EST Fri Mar 5 2021
Little question the clouds will stay away from Southwest Michigan tonight into Saturday. So, expect solid VFR conditions through Saturday evening.
A Canadian high pressure system will slowly drop southward over the next 36 hours. It's center will be crossing Lower Michigan Sunday Morning. This set up will allow the night time decoupling of the boundary layer wind field from the surface wind. That will in turn cause the surface winds more to the north. Once the sun comes back up, mixing will reconnect the boundary layer winds to the surface winds. That will cause the wind to turn more to the northwest and become gusty again, like it did today.
MARINE. Issued at 242 PM EST Fri Mar 5 2021
Small Craft Advisory continues into Saturday morning north of Pentwater as north winds stir up some choppy waves along Big and Little Sable Points.
