Good Chance Of Severe Thunderstorms For Sunday
Normally I Don’t predict rain showers simply cause it’s hard to predict. Theres alot of things that have to come together. Normally during the summer, we rarely see organized Low Pressure system so any showers are reliant on Cold Fronts. Cold Fronts help bring instability in the warm and cold air masses which converge at that boundary. Warn air rising over the Cold front will cool and condense making for the good chance of rain. Well a weak but still a cold front is moving in tonight and a slight pressure drop will bring winds out of the east making for a slight upslope flow and some instability. Now this morning, VERY little moisture was flowing up from the south. Actually the air was rather quite dry. But i noticed that during this evening that on the water vapor map that there was a slight surge of Monsoon moisture up from the south. Now if i look at wind maps and the water vapor map, if this holds through tonight and water vapor from the monsoon and some instability from the cold font combine with daytime heating, i think we up in the foot hills could see some heavy duty thunderstorms. But for denver, it’s hard to say if the storms will survive on the dry plains unless the high pressure system moves more east which it doesn’t look like doing. But i think for the mountain towns, a good rain chance will come in tomorrow. But i’ll check in the morning to see if this set up is holding much at all. If it falls apart, there will be no rain and just another hot day.
Heres the vapor Map. Look at the white areas coming up from the South West.
