Cooler & Wetter Later This Week

Good Evening!

Seasonable, spring-like weather will continue…until the weekend.  Let’s take a closer look at it all…

PLEASANT IN DENVER:  Right now in Denver we have partly sunny skies and readings of 75 at DIA, 77 Downtown at Union Station, 73 in Centennial.  We’ll see clouds in and out for the rest of the evening and seasonably mild conditions.

DRY UNTIL MIDWEEK:  Taking a look at the forecast data, zonal flow aloft, a flat ridge at the surface.  This will keep conditions fairly similar to what we have now, then on Wednesday, the first of a couple  of disturbances will rotate thru.  This initial one will be fairly weak, just enough to touch off a stray shower or two, no big deal.  We have to go clear out to the end of the three kilometer NAM model run to look at the FutureCast for 12 midnight Thursday:

As you can see here, just a few showers right along the I-25 corridor, no big deal.  The main change comes at the end of the week, as a more robust system makes it’s way into the area.  A low pressure system tracks across southern Colorado and into the Panhandles of Texas and Oklahoma, bringing a better chance for rain and some high country snow to the Metro and Front Range Urban Corridor.  Have a look at this image:

This loop runs from midnight Friday thru 6 AM Saturday.  You see the low tracking across the state, and the attendant precipitation it will touch off.  We’ll also see sharply cooler temperatures.  The 70’s we are enjoying now will be replaced by lower 50’s for Friday and Saturday!  That system gets away from us as Saturday progresses, and milder air filters back in with clearing skies.  We’ll climb back into the upper 60’s to start the new calendar week, and then back into the mid 70’s

LOOKING DOWN THE LINE:  A weak disturbance works into Colorado from the northwest the middle of next week, bringing the next substantial chance of precipitation.  Aside from that, not a whole lot to talk about in the meantime, but I will show you the latest drought map…

You see the Metro and southeastern Colorado in Moderate Drought, with most of the state east of the Rockies being too dry.  I’ll have some forecast slides up for you later this evening.  Have a good one!
