...EXPECT THUNDERSTORM ACTIVITY AND HIGHER HUMIDITY...

.DISCUSSION...
UNSETTLED WEATHER TODAY AND TOMORROW WILL KEEP HIGHER HUMIDITY
OVER THE BURN SITE AND BRING A CHANCE FOR SHOWER AND THUNDERSTORM
ACTIVITY BY MIDDAY. CLOUD COVER WILL DOMINATE MOST OF THE DAY
WITH LIGHT WINDS. A BREAK IN THE WEATHER WILL OCCUR OVERNIGHT AND
EARLY WEDNESDAY WITH ANOTHER ROUND DEVELOPING WEDNESDAY AFTERNOON.
BECAUSE OF THE HIGH HUMIDITY AND RELATIVELY SLOW MOVEMENT THESE ARE
EXPECTED TO BE WET STORMS. A DRYING TREND WILL START THURSDAY. BORSUM
