Strong cold front to blast across region Friday

Posted

Upper air pattern will amplify and produce a strong fall snowstorm across the northern plains and portions of the Rockies late this week.

Modified Canadian air mass with temperatures currently in the 20’s will plow southward down the front range of the Rockies Thursday and across Texas and off the coast on Friday.

Strong cold air advection will accompany this front with a sharp drop in temperatures of at least 15-20 degrees Friday as the front moves across the area. Many locations will see high temperatures in the low to mid 70’s prior to the frontal passage and then quickly fall into the low 60’s and eventually the 50’s by mid to late afternoon.

Strong north winds of 15-25mph will result in a very cool afternoon and evening on Friday compared to the last several months.

Will likely see both pre frontal and post frontal showers and thunderstorms on Friday, but rain accumulations will likely be on the lower side or on average .25-.75 of an inch. Post frontal cloudy skies into Friday afternoon and evening will allow the cold shallow air mass to entrench over the area quickly on Friday.

Skies will begin to clear early Saturday, but cold air advection will remain in place and only allow temperatures to warm to near 70 on Saturday even with mostly sunny skies. Most of the day will be spent in the 60’s with NE winds…so it will continue to feel “cold”.

Overnight lows Sunday morning should fall into the 50’s over nearly all of the area, except the coast where water temperatures and still very warm. Would not be surprised to see some of the western and northern areas fall into the 40’s.

Cold Canadian high pressure moves eastward later Sunday allowing a return of SE winds and heat and humidity will be back into the area on Monday along with daily rain chances.
