Monday - Tuesday: Cooler Monday with Some Rain Chances

Monday will feature the coolest temperatures over the next week in light of a cold front that had passed through the region with northeasterly to easterly surface flow and zonal flow aloft. Consequently, high temperatures will fall into the 50s to lower 60s across the region. It is important to note though that the average high at La Crosse, WI at this point in the year is in the mid-50s so we will still be near to slightly above normal on Monday. However, as we head into Tuesday, shortwave upper-level ridging and southerly surface return flow will instigate a warmer trend for the week with highs returning above normal with median high temperatures in the NBM in the middle to upper 60s.

As far as precipitation chances are concerned, an approaching shortwave impulse moving through the Great Plains will push northwest of the local area bringing some resulting rain chances, primarily north of I-90 in north-central WI and southeast MN. Currently, the latest HREF has fairly respectable probabilities (60- 90%) for measurable precipitation across southeast MN and into north- central WI. However, given that the bulk of the more robust forcing will generally remain to the northwest, more substantial rainfall amounts over 0.1" are less likely (20-50%), so not expecting any impacts from this rainfall.

Wednesday - Friday: Unseasonably Warm with Additional Rain Potential

As we head into the latter half of the work week, continued robust southerly flow into Wednesday will allow for increasing probabilities (50-90% in the NBM) for highs to top 70 degrees for much of the local area. As a result, could see some near record high temperatures at La Crosse, WI and Rochester, MN with their record highs being 75 and 73 degrees respectively for October 28th. While Wednesday currently appears to be the warmest day reflected in guidance, this unseasonably warm trend likely persists through Friday with continued zonal to southwesterly synoptic flow in place.
