AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
201 PM MDT THU MAY 8 2025
KEY MESSAGES
- WARMER WEATHER MOVES INTO THE FORECAST AREA ON THURSDAY AND
CONTINUES INTO THE WEEKEND. STILL A FEW LATE DAY SHOWERS AND
STORMS MOST DAYS.
DISCUSSION /THROUGH THURSDAY/
ISSUED AT 149 PM MDT THU MAY 8 2025
GENERALLY QUIET ACROSS THE FORECAST AREA THIS AFTERNOON, AS
RIDGING HAS STARTED TO DEVELOP TO THE NORTH/WEST OF THE REGION.
THERE'S STILL QUITE A BIT OF MID-LEVEL MOISTURE ACROSS THE AREA,
WITH A PIECE OF THE PREVIOUS TROUGH/UPPER LOW STILL HANGING BACK
ACROSS SOUTHERN CO/NORTHERN NM. THERE'S BEEN A FEW WEAK SHOWERS
ACROSS THE EASTERN PLAINS, WITH SLIGHTLY DEEPER CONVECTIVE CLOUD
COVER OVER THE HIGHER ELEVATIONS. THIS ACTIVITY SHOULD GRADUALLY
DRIFT SOUTH-SOUTHEASTWARD THROUGH THE DAY FOLLOWING THE WEAK
STEERING FLOW.
WE'LL END THE WEEK WITH FAIRLY QUIET AND WARMER CONDITIONS, AS THE
UPPER RIDGE CONTINUES TO BUILD ACROSS THE ROCKIES. HIGHS SHOULD
REACH THE 70S ACROSS THE PLAINS WITH MOSTLY CLEAR SKIES. THE
INCREASE INSTABILITY/STEEPENING LAPSE RATES OVER THE HIGH COUNTRY
SHOULD ALLOW FOR WIDELY SCATTERED SHOWERS AND THUNDERSTORMS TO
DEVELOP IN THE AFTERNOON.
OUR WARMING TREND IS LIKELY TO CONTINUE THIS WEEKEND INTO NEXT
WEEK. THE UPPER LEVEL RIDGE SHOULD STRENGTHEN A BIT MORE THIS
WEEKEND AND WILL LIKELY SHIFT A BIT MORE TO THE EAST AS A BROAD
TROUGH APPROACHES THE PACNW COASTLINE. HIGHS SHOULD AGAIN REACH
THE 70S TO LOW 80S ON SATURDAY, WITH 80S LIKELY BY SUNDAY THROUGH
TUESDAY. AS THE TROUGH APPROACHES, SOUTHWESTERLY FLOW ALOFT
SHOULD STRENGTHEN, LEADING TO A POTENTIAL INCREASE IN FIRE DANGER
FOR MOST OF THE FORECAST AREA.
THE TROUGH SHOULD RACE ACROSS THE INTERMOUNTAIN WEST BY EARLY/MID
WEEK, THOUGH GUIDANCE STILL KEEPS THE TRACK TO OUR NORTH, LEAVING
US ON THE DRIER/WINDIER SIDE. BOTH DETERMINISTIC AND ENSEMBLE HAVE
A GOOD SIGNAL FOR COOLER TEMPERATURES FOR THE LATTER HALF OF NEXT
WEEK, BUT IT'S TOO EARLY TO WORRY TOO MUCH ABOUT THAT TIMEFRAME.
AVIATION /18Z TAFS THROUGH 18Z FRIDAY/
ISSUED AT 1134 AM MDT THU MAY 8 2025
VFR THROUGH THE TAF PERIOD. SHOULD SEE SOME GRADUAL INCREASE IN
STRATOCU THIS AFTERNOON BUT LOOKS UNLIKELY TO PRODUCE ANY CEILING
ISSUES. OTHERWISE, WINDS WILL BE LIGHT THROUGH THE PERIOD WITH
SPEEDS GENERALLY UNDER 10KT.
BOU WATCHES/WARNINGS/ADVISORIES
NONE.
