Dry Conditions - High Fire Danger

Strong winds and low humidity have created a rare occurrence for this part of the country. A red flag warning has been issued due to the extreme danger of wildfire. I don't recall the last time we had a red flag warning.

From the NWS in Wilmington, Ohio...

THE NATIONAL WEATHER SERVICE IN WILMINGTON HAS ISSUED A RED FLAG WARNING...WHICH IS IN EFFECT UNTIL 9 PM EDT THIS EVENING.

VERY HIGH AND EXTREME FIRE DANGER IS PRESENT OVER THE OHIO VALLEY FOR ANOTHER DAY. A TIGHTENING SURFACE GRADIENT AHEAD OF A COLD FRONT IN THE MIDWEST WILL CREATE STRONGER WINDS TODAY...SIMILAR TO SATURDAY. THESE WINDS WILL LIKELY MIX THE ATMOSPHERE TO ABOUT 6000 FEET...WHERE VERY DRY AIR IS FOUND. COMBINED WITH THE RECEPTIVE FUELS...STRONG WINDS...AND POSSIBLE PERIOD OF LOW RELATIVE HUMIDITIES...A RED FLAG WARNING HAS BEEN ISSUED TODAY.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A RED FLAG WARNING MEANS THAT CRITICAL FIRE WEATHER CONDITIONS ARE EITHER OCCURRING NOW...OR WILL SHORTLY. A COMBINATION OF STRONG WINDS...LOW RELATIVE HUMIDITY...AND WARM TEMPERATURES WILL CREATE EXPLOSIVE FIRE GROWTH POTENTIAL.

OUTDOOR BURNING IS DISCOURAGED AND POTENTIALLY DANGEROUS AT THIS TIME. EQUIPMENT THAT MAY EMIT SPARKS OR GET VERY HOT SHOULD NOT BE OPERATED NEAR DRY GRASSES OR UNDERSTORY LITTER TODAY.
