KEY MESSAGES

- Gusty southerly winds persist for Sunday areawide. Highs warm to the mid to upper 60s under mostly sunny skies.

- Warmer temperatures return this week. Dry conditions continue with our next chance of rain not until late Friday-Saturday (20-40%).

- Strong winds gusting 30-40 mph also arrive Friday, increasing fire danger for areas with standing crops

LONG TERM /TUESDAY THROUGH SATURDAY/

The H5 ridge will amplify over most of the central CONUS through at least Friday. As the resultant 1000-500mb thicknesses expand, expect temperatures to gain a few degrees each day. Thursday and Friday appear to be the warmest days of the upcoming week, with most areas seeing highs in the mid to upper 70s. A few H5 impulses may try to ride the ridge and approach the area during that timeframe, but again, little moisture return into the area will likely limit precip development. With this forecast update, NBM suggests a less than 10% chance for precip through early Friday so expect dry conditions to prevail.

By Friday into Saturday, model guidance hints at an H5 longwave ejecting from the Intermountain West toward the Northern Plains. Lee cyclogenesis occurs with the sfc low tracking somewhere into the western Dakotas. A tight pressure gradient will set up across the area and lead to gusty southerly winds of 35 to 40 mph. Coupled with this upcoming dry spell, could see some fire weather concerns develop in areas where fuels can cure fast enough. As the mid and low level features approach the area, should see our next chance for rain by early Saturday morning (20 to 40%).

AVIATION /06Z TAFS THROUGH 06Z MONDAY/
