Hazardous Weather Outlook...UPDATED National Weather Service Hastings NE 503 PM CDT Mon Jul 10 2023 KSZ005>007-017>019-NEZ039>041-046>049-060>064-072>077-082>087- 112215- Phillips-Smith-Jewell-Rooks-Osborne-Mitchell-Valley-Greeley-Nance- Sherman-Howard-Merrick-Polk-Dawson-Buffalo-Hall-Hamilton-York- Gosper-Phelps-Kearney-Adams-Clay-Fillmore-Furnas-Harlan-Franklin- Webster-Nuckolls-Thayer- 503 PM CDT Mon Jul 10 2023 This Hazardous Weather Outlook is for south central Nebraska and portions of north central Kansas. .DAY ONE...This evening and tonight. The entire outlook area is included in either a Slight or Enhanced Risk for severe thunderstorms, with this threat lasting through at least the 10 PM to Midnight time frame for parts of the area. Generally speaking, storms will develop into the outlook area from both the north and the west with time this evening, perhaps eventually merging into a larger storm complex. The main threats with the most intense storms will be hail up to around the size of golf balls, wind gusts up to around 70 MPH and locally heavy rainfall of perhaps at least 1 to 2 inches in a short time. An isolated tornado cannot be entirely ruled out, but is certainly not the primary hazard. Eventually tonight, all thunderstorm activity will depart off to the south and southeast, and odds favor the entire outlook area being thunderstorm-free by around 2 AM. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday. For Tuesday late afternoon and evening, the majority of the outlook area is included in either a Marginal or Slight Risk for severe thunderstorms, with this threat favoring Nebraska areas more so than north central Kansas. Large hail and strong, damaging winds will be the main threats with any possible severe storms, although the likelihood of storm development and coverage of storms is still somewhat in question. Also on Tuesday, heat index values during the afternoon are expected to reach at least 100 degrees in southern portions of the outlook area, particularly within north central Kansas along with Thayer and Nuckolls counties in Nebraska. Similar to slightly higher heat index readings are expected in these same areas Wednesday afternoon, including the possibility for more dangerous readings of at least 105 degrees, particularly within parts of Rooks, Osborne, Mitchell, Jewell, Nuckolls and Thayer counties. Wednesday through Sunday, periodic thunderstorm chances remain in the forecast Wednesday through Sunday, but too many uncertainties exist to confidently pin down details with timing, location, and any possible threat for severe thunderstorms. .SPOTTER INFORMATION STATEMENT... Spotters are encouraged to report any possible instances of hail, wind gusts in excess of 50 MPH, localized flooding or anything else noteworthy. && More information may be obtained at the following web page: https://www.weather.gov/hastings Pfannkuch
