As we start a new week, we have yet another unseasonably strong cold front in the forecast.  This one, just like last week could bring us record cold temperatures later this week.

WARM UNTIL THE FRONT ARRIVES

Temperatures yesterday and today have warmed into the 80s!  We will do it again tomorrow and Wednesday.  On Wednesday, high temperatures will be close to 90 degrees!  But our strong cold front arrives Wednesday evening.  And then break out the winter coats again.

WEDNESDAY - Near 90 ahead of the cold front.  Southeast winds 10-15 mph.

COLD FRONT ARRIVAL

The cold front will arrive Wednesday evening.  With the front there will be a few scattered showers and even a few isolated thunderstorms.  It does not look like we will see much in the way of severe weather.  I can’t completely rule out an isolated severe storm in western sections of North Texas late in the afternoon as the front arrives there first.  But by the time the rain gets to DFW, the cold run will have likely surged ahead of any storms.  This would greatly limit the severe weather.  The only threat would be for some small hail.   Here’s a video I put together on April 9th about cold air undercutting thunderstorms. 

COLD FRONT LOCATION 9PM WEDNESDAY – Here is a look at where the cold front is expected to be located at 9pm on Wednesday.  It is just passing thru the DFW area.

WHY WILL IT GET SO COLD

Currently the polar jet stream is located along the northern half of the country.  See below.

By Thursday the jet stream will be plunging south right over the Plains and making it all the way to Texas.

RECORD COLD WITH THE FRONT

We will go from highs near 90 on Wednesday to Thursday afternoon temperatures in the 40s.  Not only will it be cold on Thursday, it will be cloudy and windy with gusts to 30 mph.  And throw in some spotty showers it will really be a miserable day.

Here’s a look at the dramatic drop in temperatures with the cold front.  I’m calling it a May Nosedive.  The low Friday morning of 41 degrees would tie the record low for that day.

RAIN CHANCES WITH THE FRONT
