SUMMARY FOR THE NEXT 6 DAYS -//> UPDATED FOR SATURDAY, JULY 4th at 9:15am...Today and Sunday -> A weather disturbance aloft passes through this afternoon, triggering isolated to scattered thunderstorms and showers across the area. We had to increase thunderstorm chances slightly for today, the 4th of July. Drier northwest breezes are the expected wind pattern under a ridge of high pressure aloft Sunday, and the only real moisture is expected to be in the lower levels of the atmosphere by Sunday. Therefore, we expect partly cloudy skies and a chance for afternoon and early evening thunderstorms and showers. These will be the diurnal type, triggered mostly by daytime heating, and mostly isolated in nature, so very hit and miss on the showers. The dominant weather feature is expected to be sunshine.

Monday -> A strong Gulf of Alaska low pressure system (that can bee seen ginning up in the Gulf now) moves into the northwest US, mostly Washington and Oregon, and spins off some upper air weather disturbances to help enhance the usual daily thunderstorm threat, and increase thunderstorm coverage. The winds out ahead of this low help to draw some increased moisture in also. So, we could see a more busy day as far as showers and thunderstorms are concerned, and they may be stronger storms. Thunderstorm activity may continue Monday night also, before drying winds push available moisture eastward on Tuesday.

Tuesday and Wednesday -> A strong (558-dM) low pressure system is now across the northwest US, and stronger/ drier southwest winds are expected across the Rocky Mountains. Mostly sunny skies are expected. We cannot rule out an isolated thunderstorm, especially on Tuesday, but for the most part we should be warm, windy, and mostly sunny.

Thursday and Friday -> A high pressure ridge building from the southeast displaces weakening and departing low pressure. As it does we are looking at warmer temperatures, and monsoonal moisture slowly returning. It looks like mostly a low to medium grade monsoon, with isolated afternoon thunderstorms (and not much rain) by next Friday, becoming more scattered (increased coverage) by next weekend.

--High pressure ridging returns, and becomes centered close by, and to the east somewhat, for limited subtropical moisture seeping in. T-Storm and shower activity continues isolated to scattered (10% to 40% coverage each afternoon/ evening) through mid and into late July.

--For those who want to know, it looks like an El Nino SST pattern is developing and strengthening. We would expect more moisture for thunderstorms and showers this summer, and Pacific Hurricane activity with this development. We do not think this will be a dry summer compared to average, in fact it may be a bit wet. This fall/ winter the El Nino should still be with us. This usually means a near to below average snowfaall year for northern Colorado, and near to above average snowfall for southern Colorado. That is very general, but we will try to work up some snowfall and temperature comparisions as we get closer. CM
