SATELLITE SHOWS THE UNSEASONABLY DEEP SURFACE LOW SPINNING TO
OUR EAST GENERATING THE GUSTY WINDS ACROSS OUR AREA THIS
EVENING. WE'LL SEE SURFACE WINDS WEAKEN AS THE BOUNDARY LAYER
DECOUPLES OVER THE NEXT FEW HOURS, THOUGH WINDS SHOULD STAY
AROUND 10-15 MPH OVERNIGHT OUT OF THE NORTH. SKIES WILL BE
CLEARING OF CLOUDS OVER THE NEXT SEVERAL HOURS, BUT WE'LL ALSO
SEE WILDFIRE SMOKE OUT OF CANADA AND THE PACIFIC NORTHWEST GET
PULLED IN LEADING TO HAZY SKIES FOR THE NEXT FEW DAYS.
LOOKING AT THE UPPER-LEVEL PATTERN, THE TROUGH ASSOCIATED WITH
THE LOW TO OUR EAST WILL SLIDE MORE EAST INTO THE OHIO RIVER
VALLEY OVER THE WEEKEND. MEANWHILE, RIDGING BUILDS INTO THE
CENTRAL PLAINS LEADING TO WARMING TEMPERATURES OVER WESTERN
NEBRASKA. THE GOOD NEWS FOR US IS THAT THE RIDGE AXIS NEVER
REALLY PUSHES THROUGH KEEPING THE HEAT TO OUR WEST. BECAUSE OF
THIS, WE'LL MAINTAIN MILDER TEMPERATURES THROUGH THE WEEKEND
INTO EARLY NEXT WEEK WITH HIGHS IN THE LOWER 80S ON SATURDAY AND
MID-80S TO LOW-90S SUNDAY AND MONDAY.
A TROUGH MOVING OUT OF THE GULF OF ALASKA PUSHES INTO INTERIOR
CANADA SQUASHING DOWN THE RIDGE AND BRINGING A FRONT THROUGH ON
TUESDAY. THIS WILL BRING OUR NEXT CHANCE FOR RAIN STARTING LATE
MONDAY NIGHT INTO TUESDAY MORNING. THIS FRONT APPEARS TO STALL
ACROSS OUR AREA TRIGGERING ADDITIONAL CHANCES FOR SHOWERS AND
STORMS THROUGH THURSDAY AS SHORTWAVES ALOFT INTERACT WITH THIS
FRONT. MACHINE LEARNING PRODUCTS FROM NSSL SUGGEST SOME
POTENTIAL FOR SEVERE WEATHER AS THE FRONT INITIALLY ARRIVES ON
TUESDAY, BUT A BETTER THREAT WITH THE SHORTWAVE TRIGGERING
STORMS ON THURSDAY THAT FINALLY PUSHES IT OUT OF OUR AREA. A LOT
OF DETAILS STILL TO WORK OUT, SO JUST MONITOR THESE PERIODS FOR
NOW.
CONFIDENCE IN FORECAST TRENDS BEYOND THURSDAY DROPS OFF QUITE A
BIT GOING INTO THE END OF THE WEEK NEXT WEEK AS A FAIRLY
BAROCLINIC PATTERN APPEARS TO SET UP OVER THE CENTRAL CONUS.
ENSEMBLE GUIDANCE TRENDS BACK WARMER WHICH SEEMS REASONABLE
FOR NOW.
