- Sunny and warmer
High pressure over the Missouri Valley will nose northward today resulting in plenty of sunshine. Rising heights from ridging aloft will also push surface temperatures a bit higher than yesterday.
Highs today will range from the upper 30s near US-10 to mid 40s near I-94. Tack on 10 degrees for Friday's highs. Another cold night expected due to clear skies and light winds; mid 20s expected throughout the cwa.
The next low pressure system will affect the region Friday night.
However, as warm advection gets underway, clouds will begin moving over the cwa Friday afternoon, dimming the sunshine a bit.
At this point, we anticipate precipitation holding off until Friday night.
- Chance Of Precipitation Friday Night into Saturday
The first round of precipitation in the forecast is associated with a surface low developing ahead of a mid-level wave. Ahead of this low, precipitation develops on the nose of the low-level jet in northern Illinois and moves east into lower Michigan. In general, up to 0.25 inches of precipitation is expected, highest across the southern CWA Uncertainty exists at how far north precipitation extends, however given northeasterly flow off of a canadian high pressure system, a period of sub-freezing temperatures is possible across our northeastern CWA Saturday morning. Guidance is spread on how low temps get, however if precipitation occurs with temps below freezing a period of light freezing rain is possible. Chances of both measurable precipitation occuring and temperatures being below freezing Saturday morning are around 20-30 percent across all 3 guidance suites. In addition, while the warm front will be south of the area, a period of negative 850mb LIs exists early Saturday near I94 bringing a low thunder chance. Precipitation ends later Saturday as the low pulls away. A brief period of surface ridging then occurs for Sunday bringing dry conditions.
- Additional Precipitation Possible Sunday Night into Tuesday
The approach of another surface low Sunday night brings additional precipitation chances that continue into Tuesday. Notable spread still exists in the strength of the ridging across the area Sunday, the track and tilt of the following wave Tuesday following a period of zonal flow , and by extension the track of the surface low across the region. This lends uncertainty as to the overall evolution of the system which is not uncommon in zonal flow patterns. There are even some signals (not strong at present given elevated spread) for snow for at least part of the area. Overall, confidence is high in precipitation early next week, but evolution of the system, precipitation types, and temperatures are low confidence due to the high degree of spread in solutions.
