Happy Friday to everyone! Today we are tracking a developing storm system to our southwest which looks to deposit some decent rainfall over West Texas during the next 24 hours or so.
A lead impulse frontrunning the storm system will spawn some scattered showers later this morning and into the afternoon especially across the western quadrant of our viewing area. A cold front will have made its way southward of Interstate 20 by this time. The interaction of the aforementioned impulse with the cold front will help provide a focus for showers today and tonight.
Highs north of the boundary (including Abilene) will be noticeably cooler falling through the 40s. South of the front (including San Angelo) temperatures are headed well into the 60s. Winds will blow from the northeast at around 10 mph.
Tonight the upper-level low pressure system, which will be situated over northern Mexico, begins to make its move towards West Texas. Widespread rainfall is predicted to break out by mid-late evening and stay with us through mid-morning on Saturday. Some localized heavy downpours seem a good bet at this point. Lows tonight will bottom out in the lower 40s for many of us.
Saturday the rainfall should be over with by about the noon hour. Mostly cloudy skies will persist for a period though some clearing is very possible into the afternoon. Highs will be in the middle and upper 50s.
Late night Saturday into Sunday morning a cold front in association with the exiting northeast bound storm system will bring much cooler air into our region for the back half of the weekend. Sunshine is forecasted to emerge on Sunday but temperatures will stay chilly in the mid 40s.
Monday should turn out mostly sunny but continued cool with highs struggling into the lower 50s.
Christmas Eve (Tuesday) looks to be a beautiful weather day with the mercury moving into the upper 50s to near 60 degrees.
Christmas Day (Wednesday) we track a cold front into West Texas which turns temperatures back into the lower 50s. Some clouds will accompany the front but at this time we are not looking for any rainfall.
Thursday a second stronger cold front arrives and sends temperatures to even lower levels. Highs will only make it into the upper 40s under partly cloudy skies.
