WEATHER BRIEFING: FRIDAY, NOVEMBER 17TH, 2017

HEADLINES: SHOWERS SATURDAY NIGHT, COOLER TO START THE WEEK, A LOOK AHEAD AT THANKSGIVING

We'll have another pleasant day weather-wise on Friday with our next weather disturbance remaining well off to our west. Saturday will likely be a transition day when it comes to the weather, as clouds will build throughout the day and a few showers may form along the mountain ridges in the afternoon. In addition, ahead of the surface cold front that will pass through Sunday morning, southwesterly winds will pick up on Saturday afternoon, and widespread winds of 10-20 mph, with gusts up to 25 mph, will be possible before sunset Saturday. While a fairly strong line a showers associated with the incoming cold front will move into our region late Saturday night, it currently appears that this line will weaken substantially, with our area only seeing a few light to moderate showers. As a result, total precipitation amounts outside of the mountain ridges will likely be less than one-quarter of one inch.

Once the cold front passes through early Sunday morning, cold air will start funneling into our area. High temperatures on Sunday will struggle to get out of the 40s, topping out in the low 50s thanks to mostly sunny skies. This cold shot is part of a large-scale trough that will remain in our area through the early part of the week. Temperature moderation will occur Tuesday into Wednesday as southwest winds will once again create mild and dry conditions. At present, it appears that another burst of cold air will come behind a dry cold front on Wednesday night.

Looking forward to Thanksgiving Day, the dry cold front that moves into our area Wednesday evening will allow for cool conditions on Thursday. A disturbance forming in the Gulf of Mexico will remain well to our south, meaning that dry conditions will also be present for Thanksgiving Day. At present, the forecast models are showing highs in the low 50s under mostly sunny skies.
