KEY MESSAGES: 1) Isolated thunderstorms will diminish by early this evening with high confidence for dry conditions most of this week. 2) An upper level ridge will bring hot temperatures by midweek, with moderate to high (50 to 70 percent) confidence of a few locations reaching triple digits on Thursday. WEATHER PATTERN OVERVIEW: Much of the lingering pop-up thunderstorm activity has initiated near the North Dakota border so far this afternoon and will generally remain there. The weak instability and elevated low- level moisture will move eastward as an upper level ridge arrives by Monday. Its most intense presence will be felt around Thursday, with triple digits forecast for a few locations. With very little heat so far this summer, heat safety will play a crucial role this week more than usual. There is little indication of any precipitation through the weekend, as the only caveat would be isolated convection if the ridge begins to break down. FORECAST CONFIDENCE & DEVIATIONS: Confidence is particularly high that upper ridging will yield dry weather and a warming trend in the upcoming work week. Conditions will be monitored for the potential of at least heat related advisory products in the coming days. -Zanker/Stoinskers && .AVIATION...
