We're hard-pressed to call the shallow low-level upslope pushing into the Metro area this morning a cold front, but that is technically what it is. This frontal boundary is associated with a very weak disturbance moving across the region today. We mentioned this piece of energy in our weekly outlook. On the NAM 800 mb temperature map below, we have …

The heat continues... Monday was Boulder's first official 90-degree day of the year! Denver hit 93 degrees, one shy of the record for the date. The main feature of the week, the large upper-level ridge, will be directly over-top of Colorado today (see below). Warm southwest flow will continue to flow into our region, pushing temperatures a degree or two …

The weather pattern for the week ahead will exhibit shades of the middle of summer with a ridge of high pressure parked across the south-central United States. As a result, temperatures in the Metro area will soar into the 90’s with only limited chances for rainfall through the week. This forecast doesn’t bode well for the meager snowpack remaining across the High Country.

HEATING UP! Dry and warm air will briefly invade the Front Range today from the Desert Southwest. This is in response to an approaching trough across the Pacific Northwest (shown below). Also notice the ridging present across Colorado. All of these factors will contribute to a toasty and dry day for our region. We're expecting high temperatures to climb into the upper …

Slightly stormy Wednesday Today we will see our BEST (and LAST) chance of storms for the week as residual moisture and a weak disturbance combine to produce a round of widely scattered afternoon and evening thunderstorms across the region. While temperatures will rise to near 80 degrees, we expect storms to develop across the higher elevations by early to mid-afternoon, moving …

Ridging and drier air will combine today to produce stable and thus quiet conditions across our region. The ridging can be seen in the 500 mb map below stretching from New Mexico into the Pacific Northwest. Lots of morning sunshine will fill into partly cloudy skies through the day today. There's no chance of rain with temperatures in the low …

The overall weather pattern has changed little since yesterday. The storm system we've been tracking is now located across eastern Idaho with southwest flow continuing to flow into Colorado. However, one change is that the southwesterly flow is actually now advecting in much DRIER air than it was doing earlier in the week. The GFS moisture anomaly forecast map below shows …
