Rest of the Week: Cool and Drier
Broad longwave troughing with multiple embedded shortwaves resides over the north-central U.S. through the remainder of the week, keeping a continued fetch of polar air in place and temperatures roughly 10 degrees below normal. Several of these aforementioned undulations bring short rounds of clouds and light showers, the first passing through tonight and the second during the afternoon on Wednesday. The potential for light showers dot the forecast for the rest of the week, but given the weakness of the forcing, it is tough to pin down any further specifics other than they will be quite light and of little to no impact.
The risk for any frost tonight should be minimal given the passing mid to high clouds from our first shortwave, with the potential for frost and subfreezing temperatures spreading southward for the rest of the week. Lows for early Friday and Saturday mornings will likely necessitate widespread frost/freeze headlines for the region.
Warming up for the Weekend
The pattern shifts for the upcoming weekend, allowing for a Pacific airmass to build in and temperatures to creep closer to normal. However, a look into next week shows some signal for a return to below normal temperatures (highs in the 50s), but with the region lingering on the inflection point between the longwave trough and ridge, there is modest spread between the various ensemble groups and no strong consensus on how temperatures will unfold at this point.
