DRY HIGH PRESSURE EQUALS A BEAUTIFUL LABOR DAY

PLEASE NOTE: DUE TO THE LABOR DAY HOLIDAY, THE FLOOD THREAT OUTLOOK WILL BE POSTED TOMORROW AFTERNOON, INSTEAD OF TODAY.

NO FLOOD THREAT IS FORECAST FOR TODAY.

High pressure has worked back into the state behind yesterday’s cool front, and will have a pleasant influence on today’s weather. Moisture values remain below 1 inch at all 5 of the normal reporting stations (current analysis also shows ~0.2-0.4 inches IPW across the high country) with the downward trend continuing as we move into September and the first day of Meteorological Fall. The only exception to this moisture downturn will occur over the eastern plains, where a slight uptick in low-level moisture will occur this afternoon/evening. Not coincidentally, the eastern plains are the only region with a chance for thunderstorm development this afternoon, and even then, they will be isolated at best (between 2 PM and 8 PM).

So with the drier conditions expected, the main story today will be high temperatures. The air mass is cooler as compared to yesterday, especially over the eastern plains, and that will result in a very pleasant Labor Day holiday. For specifics, please check the region-specific discussions below.


 
 

REGION-SPECIFIC FORECASTS

High Country and Western Slope:

Drier conditions are the name of the game today, as west-northwesterly winds filter across the region. Winds will be gusty at times, but wind speeds will decrease as the day moves on and the pressure gradient relaxes. This is the driest day in quite a while across the region, so get out and enjoy your holiday.

High temperatures will be in the 50s and low 60s across the higher elevations, ranging into the low-to-upper 80s across the lowest elevations. A 90 degree temperature reading or two will be reached across the far SW corner of the state.

Urban Corridor and East:

The urban corridor will stay under the influence of mostly sunny skies and seasonable temperatures, with highs in the upper 70s across the Palmer Divide, low 80s north of the Palmer Divide, and mid-to-upper 80s south of the Palmer Divide.

Further east, the plains will be mostly sunny today, with some clouds returning to the far eastern plains this afternoon with the return of low-level moisture and isolated thunderstorms. High temperatures across the plains will range from the upper 70s in the north, to mid-to-upper 80s across southern portions of area. Rain rates from any thunderstorm activity will be less than 0.3 inches/hour; gusty winds (up to 35-40 mph) and lightning will be the main threats.
