Areas of Dangerous Heat and Heavy Rain with Possible Flooding This Week

Hot temperatures and high humidity are forecast to continue across much of northeast Texas into the mid-Mississippi Valley through this week. Heavy to excessive rainfall occurring at times through Saturday could bring areas of flooding across parts of the central Plains into the upper Midwest/Great Lakes, and Four Corners states.

Aviation Forecast Discussion

.AVIATION... 06Z TAFS: VFR conditions are expected through the forecast period. There is still mostly widespread BKN/OVC coverage, but it is starting to move out of the area. Most high-res models have very high clouds or clear skies starting around 08Z. Showers have moved out of the area. There is a chance for some fog in sheltered northern valleys, but soundings indicate low confidence that fog will impact specific terminals. FORECAST CONFIDENCE AND/OR ALTERNATE SCENARIOS: High confidence in VFR conditions through the period. Low confidence in fog tomorrow morning impacting any specific terminals, but this is the highest impact alternate scenario that would result in amendments if fog does develop. /AS ----------------------- Confidence descriptors: Low - Less than a 30 percent chance Moderate - 30 to 70 percent chance High - Greater than a 70 percent chance For additional probabilistic information for NWS Spokane airports, please refer to the Aviation Dashboard on our webpage: https:/www.weather.gov/otx/avndashboard &&
