Wednesday PM Update: A Few More Rain Chances to Round out Week

Did the lightning keep anyone else up last night? What a show! Some good rain too, in a few spots, as heavy rain first developed over the Front Range foothills, then slid across the metro area early this morning.

A look at the radar for the early morning hours (2:30am or so) shows the heavy rain first over the foothills, but the pushing through downtown before dissipating. Several stations in and around LoDo reported nearly 2" of rain:

CoCoRaHS totals were generally lower, but we see a good swath of 1"+ totals from north Denver, through downtown, and southeast:

Similarly in the 24 hours HRAP analysis. Great moisture for the foothills west of town, and again across the northern metro area/downtown Denver:

Storm chances will remain pretty good today and tomorrow, with 30 to 50% rain probabilities across the region both days.

The HRRR shows best potential for rain later today across the southern and western metro area/foothills:

With the 3km NAM also focusing best chances in the foothills through early Thursday (it's got a better chance for the urban corridor tomorrow):

And finally the GEFS showing some good moisture chances today and tomorrow, before drying out (and warming up) starting Friday:

Aside from today and tomorrow, the next 10 days or so look to be on the quieter side across the area. Perhaps some additional rain chances come our way... but overall temperatures will warm to near average or a bit above average, with a good string of drier days as well for the weekend and early next week. Mountain locations, and portions of southern Colorado should remain a bit more active with better moisture feed than those of us across the northern half of the state. Ten day moisture outlook from this morning's EURO shows this:

With cooler than average temperatures shifting south/east a bit too:

Good news is, average isn't nearly as hot as it was just a few short weeks ago. The average high in Denver today is 83°F, and only creeps lower in the coming weeks. Let's hope for some rain today and tomorrow, then enjoy some beautiful September weather!
