DAYS 1-5 (MAY 21-25)<\/p>\n\n\n\n
Upper level high pressure dominates and will continue to do so through the weekend, but this doesn’t automatically mean clear skies, as you can see this morning as the sky is filled with much cloudiness from a disturbance from Canada. This is because the axis of the upper ridge is to the west and the air above us is blowing from northwest to southeast. We often see moisture and energy from the other side of the ridge, or the trough to its west, ride up and over the ridge and down its eastern side. This will continue to be the case through the weekend, which will certainly be no wash-out, but will carry opportunities to see showers (and even thunderstorms by Sunday) as a series of disturbances and finally a stronger cold front comes through. But before that cold front arrives and despite the northwesterly flow aloft, at the surface the dominant air flow is going to be from the southwest, which will work on warming our air up today and bringing the feel of mid summer along with slightly higher humidity for the weekend. Then the cold front will come through, and this sets us up for a dry and cooler Monday as high pressure drops out of Canada. But that high will keep on moving and by Tuesday it’ll be south of the region with warmer air coming back, along with more cloudiness and even another shower threat.<\/p>\n\n\n\n

DAYS 6-10 (MAY 26-30)<\/p>\n\n\n\n
Early for too many details but a shot of heat possible May 26 with showers\/thunderstorms possible, cooler\/drier following by May 27 then high pressure may hold over the region with dry weather and a warming trend thereafter.<\/p>\n\n\n\n
DAYS 11-15 (MAY 31 \u2013 JUNE 4)<\/p>\n\n\n\n
Low confidence forecast. High pressure may keep the region dry through May 31 followed by an increase in shower chances sometime in the first several days of June as an air mass boundary may be in the area.<\/p>\n","protected":false},"excerpt":{"rendered":"
