The warm weekend will be a distant memory by the time we get to the upcoming weekend.

Another strong cold front arrives Friday which will drop temperatures and bring rain.

TONIGHT – Clouds will continue to increase, but we won’t see any rain.  Temps will fall to around 50 degrees overnight.

TOMORROW – Mostly cloudy in the morning than partly sunny in the afternoon.  Another mild day with temps in the upper 60s.

WEDNESDAY – Mostly cloudy and a bit breezy.  High of 67.

THURSDAY – Rain chances will be with us starting Wednesday night into Thursday morning.  Temperatures will warm into the low 70s Thursday afternoon.

Timeline with fronts

COLD FRONT ON FRIDAY

A strong cold front will get here Thursday night into Friday morning.  There will be rain and possibly a few thunderstorms with the front.  The big story though will be the drop in temperatures behind the front.

As of Monday afternoon the front is still north of the US/Canada border.

But as the front gets here temperatures will drop thru the day on Friday with gusty north winds to 35 mph.  Below is the way the temperatures will track on Friday.

UPPER LEVEL PATTERN

There are going to be two active portions of the jet stream this week.  The upper level low in the northern branch of the jet stream will move across the northern part of the country.  While this happens another upper level low will stall over California.

Below is what the jet stream will look like on Friday.  The cold air will be driven southward thanks to the northern Low.

THE SECOND LOW

The upper level low over California will give us fits this weekend into early next week.  That low will be tracking across Texas (see below).  The question is when?

Right now it looks like the low will be close enough to North Texas on Saturday to generate a light rain.  This rain will fall when temperatures are in the 40s all day on Saturday.  But temperatures may be closer to freezing for areas of West Texas.

Below is the European model showing SNOWFALL FORECAST for West Texas.

Sunday looks to be dry.

But on Monday, the upper level low looks to finally move east.  One of my forecast models is showing the potential for some wintry precipitation on Monday, but the other model is showing temps in the 50s.

I can tell you with 100% certainty that it is going to be a cold weekend.  The item to follow on my forecast the next several days is the rain chances and possibly wintry weather for Saturday and early next week.

Stay tuned!
