And a Happy Sunday to you
Now that spring has apparently sprung under blue skies and warm temperatures it seems a lot easier to be in a good mood. (Of course those who suffer from spring allergies might dispute that statement but I digress…) After yesterday’s slightly below normal high temperature of 59 degrees at Shannon Airport today begins a string of days in which the high temperature will soar above the 70-degree mark. The pattern has definitely shifted and we are now beginning to talk about more warm weather features like the first evidence of a “Bermuda High” off the southeast U.S. coast as shown in this forecast graphic for Wednesday morning:
I inserted the white “H” to emphasize the position of the center of the high pressure system. This feature will keep us under the influence of a southerly wind for most of the week that – per the NWS Sterling forecast – could even result in high temperatures topping the 80-degree mark. BUT, there is a potential fly in that ointment that would keep that type of warmth out of the ‘Burg. Take a look at this surface feature graphic from the WPC for Wednesday morning:
Notice the frontal boundary lurking around the Mason/Dixon line? The European model has flirted with the idea that this could sag southward into the Fredericksburg region as a “backdoor” cold front and keep the 80s out of here. Right now the probabilities of that occurring are slim but not impossible so we’ll have to keep our eyes on that for Wednesday and Thursday.
Meanwhile the next storm system to slide across the Mid-Atlantic looks like it will bring some decent rainfall beginning late Thursday into Friday. Behind this system temperatures will cool down a bit but in this case “cool” is a relative term as the airmass that will follow the front looks to usher in normal high temperatures (i.e. in the 60′s) next weekend. Since that’s still several days out it’s time to enjoy a Happy Sunday today!
