401 AM EDT FRI JUN 20 2025
VALID 12Z FRI JUN 20 2025 - 12Z SUN JUN 22 2025
...STORMS, SOME SEVERE, MAY PRODUCE FLASH FLOODING OVER PORTIONS
OF THE NORTHERN PLAINS AND UPPER MIDWEST/GREAT LAKES TODAY...
...THERE IS A CRITICAL RISK OF FIRE WEATHER OVER PARTS OF THE
GREAT BASIN/FOUR CORNERS...
...DANGEROUS HEAT EXPANDS FROM CENTRAL TO EASTERN U.S. THIS
WEEKEND...
A SURFACE LOW PRESSURE SYSTEM STATIONED OVER THE NORTHERN PLAINS
ACCOMPANIED BY QUASI-STATIONARY SURFACE FRONTS DRAPED ACROSS THE
UPPER MIDWEST AND GREAT LAKES WILL PROVIDE SUPPORT FOR
THUNDERSTORMS THIS AFTERNOON/EVENING. STORMS ARE EXPECTED TO
PROPAGATE ACROSS NORTH DAKOTA THIS AFTERNOON AND INTO MINNESOTA
TONIGHT WITH MCS POTENTIAL. THE STORM PREDICTION CENTER ISSUED AN
ENHANCED RISK (LEVEL 3/5) OF SEVERE THUNDERSTORMS OVER MUCH OF
NORTH DAKOTA AND NORTHERN MINNESOTA TODAY, WHERE TORNADOES, VERY
STRONG WINDS AND VERY LARGE HAIL WILL BE POSSIBLE. A SLIGHT RISK
(AT LEAST 15%) OF EXCESSIVE RAINFALL LEADING TO FLASH FLOODING IS
IN EFFECT FOR PORTIONS OF NORTHERN MINNESOTA/WISCONSIN WHERE
MULTIPLE ROUNDS OF STORMS MAY MOVE ACROSS THE SAME AREAS THIS
AFTERNOON/EVENING. EXCESSIVE HEAT WATCHES AND WARNINGS ARE ALSO IN
EFFECT FOR PARTS OF THE UPPER MIDWEST AND NORTHERN/CENTRAL PLAINS
WHERE RECORD HIGH MINIMUMS MAY BE REACHED TONIGHT--FUELING
AFOREMENTIONED STORMS. SHORTWAVE ENERGY ROUNDING AN UPPER RIDGE
WILL BRING ADDITIONAL HEAVY RAIN AND SEVERE STORM POTENTIAL TO THE
LOWER GREAT LAKES AND INTERIOR NORTHEAST ON SATURDAY.
A DEEP UPPER-LEVEL LOW WILL MOVE INTO THE WEST THIS WEEKEND,
BRINGING COOLER TEMPERATURES TO THE REGION AS WELL AS RENEWED FIRE
WEATHER CONCERNS. THERE IS A CRITICAL RISK OF FIRES FOR PORTIONS
OF THE GREAT BASIN AND FOUR CORNERS REGION THIS WEEKEND, DUE TO
VERY DRY AND WINDY CONDITIONS BENEATH THE BASE OF THE UPPER
TROUGH. ELSEWHERE, AN UPPER RIDGE WILL AMPLIFY OVER THE EASTERN
U.S. THIS WEEKEND, LEADING TO POTENTIAL RECORD TEMPERATURES AND
HEAT RISK CONCERNS NEXT WEEK.
