Latest satellite imagery showing clear skies early this morning along with a few localized areas of patchy fog. Temperatures currently ranging in the upper 60s with dew points in the mid 60s. The forecast remains on track with the main weather story now being a well advertised heat wave ramping up this weekend. A very anomalous upper-level high builds over the western CONUS today which is progged eastward and deepens as it moves into the northern plains, Sunday. Weak southerly flow will continue to advect dew points into the upper 60s to a few lower 70s with surface highs reaching near 90 degrees for most of us west of the St. Croix River Valley. Western Wisconsin counties will range in the upper 80s. With increased dew points temperatures, WBGT values will reach the low 80s by late morning and heat indices reaching the mid to upper 90s. As of now, these conditions fall shy of heat advisory criteria but it is important to remain hydrated and stay in the shade, wear light colored clothing, and take breaks when needed to avoid heat illnesses.

Sunday into early next week features the continuation of the this heat wave with lack of precipitation chances until later in the week. On Sunday through Tuesday, forecast high temperatures will reach the low to mid 90s with dew points remaining elevated in the upper 60s to low 70s. This will allow for heat indices once again to creep near 100 degrees. As of now, conditions look like we should dodge Excessive Heat conditions however Heat Advisories will likely be needed starting Sunday and persisting through Tuesday. By late week, a weak surface low tries to bring in some rain chances mainly for northern and eastern MN, and western WI, however NBM PoPs advertise only low-end chances (sub 20%) at this time. Nonetheless, given the warm forecast this week, conditions do make for great opportunity to take advantage of lakes, community pools, splash pads, etc. to help bring some relief from the heat. I'll leave you this nice fact to "cool" you off as well. We are only 119 days from our average first snowfall for the year (November 6th).
