LUNAR ECLIPSE

FIRE DANGER RETURNS FRIDAY

The tail end of spring break will bring us more rounds of fire danger. Highs tomorrow will once again reach the 90s. We’ll begin the day with a brief round of morning clouds and humidity. That quickly gets erased by lunchtime, as westerly winds kick in. The strongest gusts will be north of the area, but some gusts of up to 30-40 mph are possible. This will present an extreme fire danger for much of the area. A Red Flag Warning has been issued. The key timeframe to be on alert for fire danger is noon to 9 p.m..

SATURDAY BRINGS STRONGEST WINDS

While it’ll be cooler on Saturday (highs in the upper 70s), winds gusts will become stronger. West winds gusting up to 35-45 mph are possible. This will be paired with very low humidity, creating another round of extreme fire danger.

COOL MORNINGS SUNDAY, MONDAY

The lower humidity will allow temperatures to fall during the morning hours Sunday and Monday mornings. In fact, we’ll dip into the upper-40s by early Monday. Jackets may be required as kids head back to school.
