..Heat this weekend

Ridging and ensembles all point to a return to heat impacts Saturday and especially Sunday. Dew points will be in the 60s, bringing heat index values into the 90s for Saturday and above 100 for Sunday. While heat index values will be meeting criteria for advisory mainly Sunday, there are other indicators of high heat impacts. Wet bulb globe temperatures on Saturday will be well into the 80s, and mid 80s by Sunday. Heat risk should be well into the major category over the weekend, and there is a 30 to 50 percent probability of extreme heat risk for the southern Red River Valley on Sunday. Not quite ready for headlines, but will have to watch this weekend closely.

VFR conditions with some high level smoke coming in from the west. Expecting smoke to thicken as we move into tomorrow, but at this point the chances for it getting down to the surface are pretty low, so will leave out of visibility for now. Winds that are currently southwest with some gusts to 20 kts will settle down a bit around sunset. Then pick up again with gusts into the 25 to 30 kt range by the end of the period.
