...SEVERE THUNDERSTORMS AND FLASH FLOODING POSSIBLE ACROSS
PORTIONS OF THE CENTRAL PLAINS AND MIDWEST TODAY...
...UNSETTLED WEATHER WITH THE POTENTIAL FOR HEAVY RAIN AND STRONG
STORMS ENTER THE LOWER GREAT LAKES AND UPPER OHIO VALLEY ON
SATURDAY...
...DANGEROUSLY HOT CONDITIONS WILL CONTINUE FROM PARTS OF THE
SOUTHERN PLAINS TO THE SOUTHEAST THIS WEEKEND...
A LOW PRESSURE SYSTEM IS PUSHING ACROSS THE NORTHERN AND CENTRAL
PLAINS THIS AFTERNOON. THE LOW PRESSURE CENTER IS MOVING EAST
ALONG THE U.S.-CANADA BORDER WITH A TRAILING COLD FRONT EXTENDING
SOUTH AND WEST FROM THE UPPER MISSISSIPPI VALLEY THROUGH THE
CENTRAL PLAINS AND A WARM FRONT LIFTING NORTH ACROSS THE MIDWEST
AHEAD OF THE SYSTEM. CONDITIONS WILL BE FAVORABLE FOR SCATTERED
SEVERE THUNDERSTORMS TO DEVELOP THROUGH THIS EVENING, AND
POTENTIAL STORM HAZARDS MAY INCLUDE LARGE HAIL, DAMAGING WINDS,
AND A COUPLE OF TORNADOES. STRONG STORMS MAY ALSO PRODUCE LOCALLY
HEAVY RAINFALL THAT COULD LEAD TO INSTANCES OF FLASH FLOODING,
PARTICULARLY IN AREAS WHERE SOILS ARE SATURATED FROM RECENT HEAVY
RAINS AND AREAS WHERE TRAINING/REPEATING STORMS DEVELOP.
THE LOW PRESSURE SYSTEM WILL TRACK EASTWARDS ON SATURDAY, SLOWLY
MOVING ACROSS THE UPPER GREAT LAKES REGION, WITH THE TRAILING COLD
FRONT EXTENDING BACK THROUGH THE OHIO AND MIDDLE MISSISSIPPI
VALLEYS TO THE CENTRAL PLAINS AND SOUTHERN ROCKIES AND WITH THE
LEADING WARM FRONT LIFTING ACROSS THE MID-ATLANTIC INTO THE
NORTHEAST. SHOWER AND THUNDERSTORM CHANCES WILL SHIFT EAST WITH
THE SYSTEM, AND SOME STORMS MAY BECOME SEVERE ON SATURDAY. THE
MAIN STORM HAZARDS WILL INCLUDE SCATTERED DAMAGING WINDS, A COUPLE
OF TORNADOES, AND LOCALLY HEAVY DOWNPOURS. DUE TO THE SLOW MOVING
NATURE OF THE SHOWERS AND STORMS, ISOLATED TO SCATTERED INSTANCES
OF FLASH FLOODING WILL BE POSSIBLE ALONG THE ENTIRE LENGTH OF THE
COLD FRONT.
ON SUNDAY, THE SYSTEM WILL GAIN A BIT MORE MOMENTUM, AND THE
CENTRAL LOW WILL PUSH INTO SOUTHEASTERN CANADA WHILE THE TRAILING
COLD FRONT MOVES TOWARDS THE EAST COAST. MEANWHILE, ANOTHER LOW
PRESSURE SYSTEM WILL DEVELOP OVER THE PACIFIC NORTHWEST/SOUTHERN
CANADA, WHICH WILL BRING PRECIPITATION CHANCES BACK TO THE PACIFIC
NORTHWEST ON SUNDAY THAT WILL SPREAD INTO THE NORTHERN AND CENTRAL
PLAINS ON MONDAY.
DANGEROUS HEAT WILL CONTINUE TO BE A MAJOR WEATHER STORY THROUGH
THE LAST COUPLE DAYS OF JUNE AS AN UPPER LEVEL RIDGE STRENGTHENS
OVER THE SOUTH-CENTRAL U.S. AND THE SOUTHEAST. THIS WILL LEAD TO
ABOVE AVERAGE TEMPERATURES IMPACTING AREAS FROM THE
CENTRAL/SOUTHERN PLAINS TO THE SOUTHEAST, WITH SUMMER HEAT ALSO
BUILDING ACROSS THE SOUTHWEST AND NORTHERN HIGH PLAINS BY SUNDAY.
HIGH TEMPERATURES ARE FORECAST TO REACH THE UPPER 90S AND LOW 100S
IN THE SOUTHERN PLAINS AND LOWER MISSISSIPPI VALLEY TODAY, WHERE
EXCESSIVE HEAT WARNINGS AND HEAT ADVISORIES ARE IN EFFECT.
SCATTERED AFTERNOON THUNDERSTORMS MAY KEEP THE SIZZLING HEAT AT
BAY ACROSS THE SOUTHEAST, BUT HIGHS INTO THE MID-90S CAN STILL BE
EXPECTED THIS WEEKEND. IF SPENDING TIME OUTDOORS BE SURE TO FOLLOW
PROPER HEAT SAFETY BY TAKING FREQUENT BREAKS, STAYING HYDRATED,
AND CHECKING ON NEIGHBORS.
