Will the arrival of a cooler airmass keep high temperatures at Grand Junction below 90-degrees? It's looking like it! Forecast high temperatures over the next several days are in the upper 70's to the mid 80's. If we don't hit 90-degrees any more in 2018, we will remain tied with 1977 for the most number of 90-degree days in a year.
Isolated showers will dissipate by late this evening as dry northwesterly flow moves into the area behind today's cold front. Temperatures will be chilly in some areas tonight, especially up in northwest Colorado where some of the lower valleys will drop below freezing. Dry weather will prevail through the rest of the work week with temperatures slowly rebounding back to above seasonal normals by Thursday.
