KEY MESSAGES
* DRY CONDITIONS, BREEZY AFTERNOONS, AND GRADUALLY WARMING
TEMPERATURES WILL CONTINUE THROUGH THE MIDDLE OF NEXT WEEK.
DISCUSSION
TODAY THROUGH WEDNESDAY.
A BROAD UPPER-LEVEL TROUGH WILL REMAIN ACROSS THE SOUTHWEST THROUGH
THE END OF THE WEEK. BREEZY CONDITIONS CAN BE EXPECTED EACH
AFTERNOON WITH SOUTH TO SOUTHWESTERLY WINDS AROUND 20 MPH COMMON,
ALTHOUGH STRONGER WINDS CAN BE EXPECTED OVER HIGHER TERRAIN. THESE
BREEZES, ALONG WITH THE CONTINUING DRY CONDITIONS, WILL ELEVATE FIRE
DANGER AS WE HEAD INTO THE HOLIDAY WEEKEND. AS INDEPENDENCE DAY
ACTIVITIES INCREASE, INCLUDING COOKING ON CHARCOAL GRILLS AND USING
SAFE-AND-SANE FIREWORKS, PEOPLE ARE ENCOURAGED TO PRACTICE FIRE
SAFETY AND ENSURE ADEQUATE WATER IS READILY AVAILABLE IN CASE A FIRE
STARTS. OVER THE WEEKEND, THE TROUGH WILL FINALLY WEAKEN AND SHIFT
EAST, ALLOWING HIGH PRESSURE TO BUILD OVER THE FOUR CORNERS REGION.
TEMPERATURES WILL GRADUALLY INCREASE THROUGH THE FORECAST PERIOD,
WITH WIDESPREAD MODERATE HEAT RISK (LEVEL 2 OF 4) EXPECTED BY MONDAY
AND CONTINUING THROUGH MIDWEEK NEXT WEEK. LONG-RANGE GUIDANCE ALSO
INDICATES THAT MONSOONAL MOISTURE MAY BEGIN TO MOVE INTO PORTIONS OF
THE FORECAST AREA LATER NEXT WEEK.
