You Want Cold? I'll Give You Cold!
9:50 AM Friday Update... Remember this is ONLY 1 model showing this, but I wanted to throw this out there. Remember, this is NOT our forecast at this time, but I'm watching it carefully. I have mentioned below the chance for some of the rain to change over to some snow flurries as the precipitation comes to an end Monday morning. IF something like this were to happen, remember while it would be much colder, temperatures at the surface will be above freezing and the ground temps will be warm as well from all the warmth lately.
This data is from the NAM and it's the BUFKIT profile for Little Rock. I'll explain what it means below the picture.
The much talked about cold front here on the blog will blast through the state late Sunday, but let's put this into a little perspective.
The average high temperature this time of the year is in the mid 50s. Readings for the first several days of this month were close to 20 degrees ABOVE that average. Now, I think Monday and Tuesday will have the potential to only make it into the mid 40s at best. That's about 10 degrees below that average. So this is nothing unusual, but it will be a shock to many of us considering how warm it has been. Do the math and there will be a 30-35 degree swing in regards to our high temperature. So the bottom line, it's going to finally feel like December and early winter and I'm extremely happy about that. According to the poll on the right, it looks like many of you are as well.
Also, there's something new I haven't done before. Check out the countdown clock to the right. This is the estimated time of arrival of the onset of colder air and it could be off by an hour or two. I'll adjust it as we get closer.
Not only will there be colder air, but there's a very slight chance for a snowflake or a little sleet. THIS WILL NOT BE A BIG DEAL AND THE CHANCE IS VERY SMALL. ANYTHING WILL BE LIGHT. Remember, temperatures will be still above freezing, most of the moisture will be gone, and surfaces are still warm. I'll explain below.
As I always tell you, "never say never to Arkansas weather". We have the risk for some strong to severe thunderstorms late today...
Active may be an understatement when it comes to the weather over the next 5 days. The first round of rough weather arrives Wednesday after...
Last Saturday we started to see the possibility for a tropical system to affect Arkansas. It's looking more and more likely at least so...
