Major Storm to Impact Colorado through Sunday

nws-national-weather-service-logo

An evolving storm system currently across the Pacific Ocean will track through the Pacific Northwest and Great Basin. Forecast models are coming into much better agreement with regard to the positioning and strength, with the center of the system around the Four-Corners by early Saturday morning.

First, an elevated risk for extreme fire behavior exists Thursday afternoon and early evening Thursday across most of the southeast plains.

A small part of far southeast Colorado may also have an elevated risk for extreme fire behavior Friday afternoon. Currently Baca and Prowers Counties are not included in the Red Flag Warning for today.

On Friday, thunderstorms will develop across the southeast plains and I-25 corridor, and there will be a slight risk for severe storms across most of the southeast plains into the I-25 corridor Friday afternoon and evening. At the same time, snow will develop across the higher terrain.  As time progresses, the risk of heavy snow accumulations and heavy rain will exist from later Friday through Saturday, and perhaps lingering into Sunday.

Non-severe storms will occur over parts of the area Thursday, with a risk for storms producing damaging hail and winds, and a tornado or two Friday afternoon and evening. There is a smaller possibility that severe storms could again occur during Saturday across the far southeast plains.

In addition, there is the distinct possibility of heavy precipitation totals across the area. Rain amounts of a couple to several inches across the I-25 corridor and southeast plains would cause high water flows and potential flooding.  On top of that, across the high country heavy snow is a distinct probability.

The weekend forecast for Lamar and the surrounding area calls for strong winds and some potential for heavy rainfalls.
