- Increasing Chance for Showers/Storms Later Saturday into Saturday night
Southerly winds ahead of an approaching cold front will draw up moisture from the south Saturday into Saturday night. Instability increases as well later Saturday afternoon into Saturday night, but overall remains weak. Aloft some upper level divergence is seen Saturday night over the CWA so that may enhance the lift.
Thus the combination of moisture, lift and instability will likely lead to showers and a few storms. Ensemble QPF values, while low, have been trending up with the precipitation for this period.
- Dry end of the weekend
High pressure over the upper Mississippi Valley will produce plenty of sunshine Sunday. Highs will climb to a couple of degree either side of 70.
- Many chances for rain next week
The persistent upper trough over the western US is progd to cut off over the northern High Plains during the middle of the week. The result will be several short waves that move in our direction and bring chances for showers and storms.
Tuesday night through Wednesday night will be a time frame that will see increased chances for precipitation. An occluded front will lift north toward Lower MI Tuesday afternoon and this will produce some showers/storms. Present indications are that the strongest instability will remain south of the state. However, that could changed this far out. SPC has already highlighted areas to the southwest of the state for the potential of severe storms.
Another chance of showers/storms will come Thursday and Thursday night, when the surface low over the northern Plains moves east.
Accompanying short waves and a feed of moisture rich air from the south will spur convective development during this time.
AVIATION /00Z TAFS THROUGH 00Z SUNDAY/
Issued at 757 PM EDT Fri May 3 2024
A combination of lingering low level moisture that will not decrease substantially behind this afternoon's cold frontal passage and a flow off of Lake Huron will produce stratus and fog tonight. We will be VFR through any flights at the TAF sites through 05Z or so. After 05Z, the stratus and fog will be making a push into Southwest Lower Michigan from the east. MVFR and IFR ceilings will develop at LAN and JXN around 06Z and overspread GRR/BTL and AZO by 09Z. The stratus will press into MKG by 11Z.
The lowest conditions, IFR and potentially LIFR will occur between 09Z and 13Z. Low clouds will lift to VFR through the daylight hours of the Saturday morning (12Z-16Z). VFR weather is expected Saturday afternoon. Winds will become east tonight and gradually become southeast and south on Saturday.
MARINE
Issued at 231 PM EDT Fri May 3 2024
Southerly flow will be on the increase Saturday into Saturday night as a front moves in from the west. This will be warm air advection and overall the values are expected to remain under 20 knots. Thus we don't plan on needing headlines a this time.
