At Stevens Field the high yesterday was 76 and the low this morning was 48. The peak wind at the airfield yesterday was 21mph.
Many of us got measurable precip yesterday. The rain lottery winners were the upper Piedra where I saw 0.75” reported on Weather Underground.
*** The Grand Junction National Weather Service has issued a Flash Flood Watch valid from noon through this evening for the San Juan Mountains. *** This does not include Pagosa Springs. However, afternoon showers and thunderstorms are capable of dropping large amounts of rain in short periods anywhere in our area. Be careful around low-lying areas, drainages, and streams.
This is the last day the ingredients are in place for widespread heavy showers and thunderstorms. The second half of the week the monsoonal moisture plume will weaken, and precipitable water and capes will decrease so afternoon showers and thunderstorms will be more isolated.
Today… Will be the most active day of the rest of the week. In the high country the first showers and thunderstorms can develop between 11 and noon and over the valley between 1 and 2pm. The best chance for showers and thunderstorms is 2 to 6pm with a lesser chance until midnight. Expect brief periods of heavy rain, small hail, gusty winds, and lightning.
Highs will be in the lower to upper 70s. Lows will be mid-40s to mid-50s.
Afternoon winds will peak around 20mph though isolated convective gusts to 40mph are possible near showers and thunderstorms.
Tomorrow through Monday… The monsoonal moisture plume will dwindle. Afternoon showers and thunderstorms will be more isolated with the best chance tomorrow. High temps will be upper 70s to mid-80s and lows will be mid-40s to mid-50s.
