Rain slips into the North Texas forecast late Friday and early Saturday with a major change in the upper level pattern sending arctic air south into Texas by Tuesday, according to the U.S. National Weather Service.
A 30 percent chance of rain is possible Friday night with a 20 percent during the day Saturday. Temperatures will dive to the mid-30s Saturday through Monday night with highs ranging from the mid- to upper-40s Saturday and Sunday and a high of 55 on Monday.
Forecasters are watching the position, track and strength of an upper level low that will begin moving into the area by Tuesday.
The upper level low will determine whether North Texas will see wintry precipitation around or after New Year’s Day.
Three ingredients are needed for winter precipitation: cold air, moisture and lift.
The upper level low will be responsible for the amount of moisture and lift seen over the region, but it is too soon to know for sure how much.
Currently, the forecast data favors a low chance of freezing rain (with snow looking unlikely) as there may not be enough moisture or lift for a major winter weather event.
The highs for Wednesday and Thursday are expected to be in the mid-30s with lows dipping to the high 20s.
