Pinpoint Weather Alert Day: Heavy mountain snow expected Thursday

Forecast: The 90s roll on; thunderstorms return late weekend

Data pix.

We officially hit 90 degrees yesterday.  It was our first 90 of the year.  I'm forecasting 92 today.

Skies stay mostly sunny today with a small 10% chance of an afternoon dry, gusty thunderstorm.

We average 30 90-degree days per year in Denver.

The mountains can expect morning sun turning partly cloudy this afternoon.  Just a small 10% chance of an afternoon t-storm.  Highs 60s, 70s, and 80s.

Friday is the hottest day of year so far at 94.  Dry.

90°-95° on Saturday.

A better chance (40%) of afternoon thunderstorms arrives on Sunday and Monday.  Temps cool into the low to mid 80s as a result.

Why the change?  A large dip in the jet stream currently in the Pacific Northwest moves east and begins to affect Colorado's weather.
