Much Colder Temperatures This Weekend

From Chief Meteorologist Brandon Rector...

The above average temperatures continued for us again today. Highs were in the upper 70s to low 80s. That is about 20 degrees above average for this time of year.

If you didn't have a chance to enjoy the beautiful weather today, you have one more chance tomorrow before the pattern changes for us. Highs on Saturday look to be in the upper 70s to low 80s again. It will be a bit breezy tomorrow with winds from the south-southwest. We should see mostly cloudy skies by the end of the day. For those of you heading out to the Abilene and Wylie playoff games in the Metroplex, the weather should be fine. It doesn't look like you will need the rain gear.

A cold front is expected to move through the area on Sunday. We will see our highs for the day occur in the morning with temperatures tumbling through the afternoon. Right now, morning temperatures look to be in the upper 50s to low 60s with afternoon temperatures in the mid 40s to low 50s. There is a 40% chance of showers and thunderstorms for the second half of the weekend.

An upper level trough will remain to the west of us Sunday and Monday. It should move towards us on Tuesday and pass us by to the north on Wednesday. We will see periodic upper level disturbances during this time period. With enough moisture in place, there is a good chance for precipitation as well. That chance is 40% on Sunday, 50% on Monday and Tuesday and 20% on Wednesday. Highs for Monday through Wednesday are expected to be in the upper 30s to low 40s with lows in the upper 20s to low 30s. This means that we could see rain change over to freezing rain and/or sleet Sunday night into Monday morning, Monday night into Tuesday morning and Tuesday night into Wednesday morning. During the day, the precipitaiton would likely just be rain. However, if the precipitation stays constant and heavy enough throughout the day or the airmass is colder than anticipated our highs could be lower. Therefore, we could see freezing rain and sleet throughout the day. The best chance of seeing the frozen precipitation will be in the northern half of the Big Country. Obviously we have had warm temperatures lately, so the ground is too warm to support frozen precipitation right now. The main problems, if there were to be any, would be on elevated objects, bridges and overpasses. We will be keeping a close eye on this situation so stay tuned to KRBC for the latest weather updates.

Thursday and next Friday look dry right now with highs in the low 50s.

Have a super Saturday!
