BRINGING WARM AND DRY CONDITIONS. HIGH TEMPERATURES TODAY WILL BE
IN THE LOW 70S TO LOW 80S, INCREASING TO LOW 80S TO LOW 90S BY
WENDESDAY.
A DISTURBANCE MOVING ACROSS NORTHERN MONTANA LATE TONIGHT THROUGH
MONDAY WILL BRING BREEZY WINDS OUT OF THE NORTH, WITH WIDESPREAD
GUSTS OF 25 TO 40 MPH. GIVEN THE DRY AND BREEZY CONDITIONS MONDAY,
ALONG WITH HIGHS 10 TO 20 DEGREES ABOVE NORMAL TODAY AND MONDAY,
THERE ARE SOME INCREASED GRASS FIRE CONCERNS, ESPECIALLY FOR AREAS
NORTHEAST OF BILLINGS. TAKE CARE NOT TO CAUSE A SPARK!
THERE ARE SIGNS OF AN UNSETTLED PATTERN DEVELOPING THE SECOND HALF
OF THE WEEK. THERE IS STILL SIGNIFICANT DISAGREEMENT BETWEEN
MODELS, BUT THERE IS MODERATE CONFIDENCE FOR DAILY SHOWERS AND
THUNDERSTORMS TO DEVELOP AND HIGHS TO RETURN TO 70S AND 80S.
