TONIGHT THROUGH SATURDAY...
WE HAD OUR ONE NICE, PLEASANT DAY WITH AFTERNOON SUNSHINE BOOSTING
TEMPERATURES INTO THE MID 70S ACROSS THE REGION UNDER A WEAK RIDGE
OF HIGH PRESSURE. HOWEVER, GLOOMY WEATHER IS SET TO TO RETURN THE
THE MID MISSOURI VALLEY TONIGHT AND LIKELY PERSIST THROUGH SATURDAY.
THE FIRST IN A SERIES OF SHORTWAVES IS CURRENTLY APPROACHING FROM
WEST, AND WILL REIGNITE SHOWERS ACROSS THE REGION TONIGHT. WHILE A
FEW RUMBLES OF THUNDER CAN'T BE RULED OUT, OVERALL INSTABILITY WILL
REMAIN WEAK AT BEST THROUGH SATURDAY. SUBSTANTIAL GULF MOISTURE WILL
REMAIN OVER THE CENTRAL CONUS, WITH PWATS RISING TO 1.5"-2". LREF
PROBS ESTIMATE A 50-70% CHANCE OF SEEING MORE THAN 1.5" THROUGH
SATURDAY AND A 30-45% CHANCE OF SEEING GREATER THAN 2" OF RAIN.
PRECIPITATION CHANCES WIND DOWN SATURDAY AFTERNOON AND EVENING,
ENDING FROM WEST TO EAST. TEMPERATURES SATURDAY AFTERNOON WILL BE
DEPENDENT ON HOW QUICKLY CLOUD COVER CLEARS OUT OF THE REGION. IF
AFTERNOON SUN MANAGES TO PEAK THROUGH, HIGHS WILL LIKELY REACH INTO
THE MID 70S. HOWEVER IF CLOUD COVER PREVAILS, LOOK TO TEMPERATURES
TO REMAIN SIMILAR TO THURSDAY AND FRIDAY, IN THE 60S TO LOWER 70S.
SUNDAY AND BEYOND...
ANOTHER BRIEF RIDGE WILL BUILD INTO THE REGION SUNDAY, GIVING US
ANOTHER GLIMPSE OF SUNSHINE AND DRY WEATHER. AFTERNOON HIGHS WILL
LIKELY REACH THE 70S.
MIDLEVEL THERMAL RIDGING AHEAD OF THE NEXT TROUGH AND SURFACE COLD
FRONT WILL ALLOW TEMPERATURES TO REMAIN IN THE 70S ON MONDAY, BEFORE
SHOWERS AND STORMS RETURN TO THE REGION. LONGER RANGE MODELS
CONTINUE TO HINT AT THE POTENTIAL FOR STRONG MOISTURE ADVECTION INTO
THE REGION WITH THIS NEXT SYSTEM MONDAY THROUGH WEDNESDAY,
POTENTIALLY SUPPLEMENTED BY MOISTURE FROM HURRICANE POLO OFF THE
WESTERN COAST OF MEXICO. GIVEN THE WELL-SATURATED SOIL CONDITIONS
AND POTENTIAL FOR ANOTHER ROUND OF HEAVY, ABUNDANT RAINFALL, AREAS
OF FLOODING MAY VERY WELL BE A POSSIBILITY. IN ADDITION TO
POTENTIALLY HEAVY RAIN, A MORE UNSTABLE AND SHEARED AIR MASS COULD
LEAD TO THE FORMATION OF STRONG TO SEVERE STORMS, AS IS HIGHLIGHTED
BY A 5-10% PROBABILITY IN MACHINE LEARNING GUIDANCE.
