LOOKING GREAT WITH HIGHS IN THE UPPER 60S FOR WEDNESDAY. A WARM FRONT LIFTS NORTH IN THE MORNING. MOST OF THE RAIN IN THE MORNING IS TO OUR NORTH OR OUT TO THE WEST. SO I THINK WE CAN SQUEEZE BY WITH SOME DRY TIME ON WEDNESDAY MORNING. BUT NOTICE RIGHT IN THE MID PART OF THE DAY WE GET A LINE OF SHOWERS THAT COME THROUGH HERE AND THEN A COLD FRONT LATE THAT COULD BRING A FEW RUMBLES OF THUNDER LATE ON WEDNESDAY INTO WEDNESDAY NIGHT. SO WE’LL KEEP YOU UPDATED ON THOSE CHANCES AND CHANCES FOR BENEFICIAL RAINFALL. NOW NOTICE OUR RAINFALL THROUGH WEDNESDAY EVENING IS ABOUT A 10TH OF AN INCH, MOST OF THAT FALLING ON WEDNESDAY AFTERNOON INTO THE EVENING HOURS. WE COULD EVEN SEE SOME SLIGHTLY HIGHER TOTALS DEPENDING ON IF YOU GET A THUNDERSTORM LATE THURSDAY, IT’S GOING TO BE COOL DOWN TO 62 DEGREES. LOOK AT FRIDAY THOUGH. WE BOUNCE BACK TO 70. THAT’S MORE LIKE IT FOR MID MAY. SATURDAY WE’RE UP TO 76 DEGREES. A MUCH WARMER WEEKEND. SUNDAYS AT 80. AND NEXT WEEK WE CONTINUE THAT 80 DEGREE TREND ON MONDAY AND TUESDAY BEFO
