Riverfest is coming to an end...Memorial Day weekend is almost done...and if you haven't noticed our weather pattern is changing...in a good way. In the last few days, our flow in the upper level of the atmosphere is shifting to a summer pattern. A large upper level high pressure system is developing overhead. This shift in the flow is leading to more sunshine and, of course, hotter temperatures.
MEMORIAL DAY: Similiar to the weekend, this Memorial Day will be hot and bright. A few low lying clouds will surge into the southern border of Arkansas early in the morning but will fade away by the time you're heading out for lunch. Temperatures will make a run for the low 90's yet again.
REST OF THE WEEK: The upper level high pressure system I just mentioned will stick around for the short work week, so you can count on more sunshine and hot temperatures (mid 90's). Heat index values will approach the century mark later in the week. Keep that in mind if you plan on being outside for a lengthy period of time.
NEXT WEEKEND: Here is a sneak peak of what to expect for the first weekend of June...I'm seeing signs from the models that the upper level high pressure system (or ridge) will eventually break down by Saturday allowing a small disturbance to slide in from the southeast on Sunday. Since we'll have a good amount of moisture in place and some good old fashion daytime heating, we could see Mother Nature squeeze out some thunderstorms late on Sunday. They don't look severe but they'll be a change of pace compared to what we'll go through this week.
That's it weather fans. Enjoy the rest of your 3 day weekend and be safe out there.
