DENVER(CBS)- A surge of cooler air and moisture backing into the Front Range from the north/northeastern corner of the state fired up rare early morning thunderstorms from Weld down into Elbert counties. Heavy rain and lighting greeted folk from Fort Morgan down to Byers from 4am through 7am Thursday morning.
The cold front pushed in cloud cover over the Front Range that will help to slow the warming of afternoon temperatures.
Even with the clouds there should be enough heat to fire up a few isolated thunderstorms late in the day. With some of the storms east of Denver lasting into the night.
A few of these Thursday storms could reach severe levels which would be 58 mph winds and higher along with the potential for 1 inch size hail or larger.
On the big forecast weather map we are watching a ridge of high pressure centered over Las Vegas that will slowly move into the southern Rockies for Friday into the weekend.
This will bring in warmer temperatures while at the same time moisture will override the ridge and bring in a better chance for afternoon storms through the weekend.
