FTB 09-28-2019: Windy and Mainly Dry

Issue Date: 9/28/2019
Issue Time: 7:16 AM


If you take a look at the upper-air analysis below, you will notice the main features for today’s forecast. The upper-level low, marked by the red “L,” is in the process of deepening along the west coast, and in response, strong, southwesterly flow aloft (maroon arrows) has settled in across the Central and Northern Rockies. This strong, southwesterly flow will serve two purposes today: 1) it will allow for the development of a couple isolated, high-based showers over the High Country, and 2) it will lead to very gusty winds over the High Country.

East of the mountains, a strengthening surface low over eastern Wyoming will bring gusty, southerly winds to the area. The breezy conditions will allow temperatures to warm to pleasant levels, with highs in the 70s/80s for most of eastern Colorado, with a few locations remaining in the mid-to-upper 60s over the Palmer Ridge and in the far Northeast Plains where a bit of cloud cover this morning will hinder full daytime heating.
