DAYS 1-5 (MAY 11-15)<\/p>\n\n\n\n
The large scale pattern has now shifted from one block to another as part of the transition to the “hybrid” pattern I have referenced several times recently. Previously, the Omega pattern existed – cut off low western US, cut off low eastern US, ridge of high pressure between the two. Now, it’s a Rex Block – high pressure to the north, low pressure to the south, located over the central and eastern US. This pattern persists the next few days before itself starting a shift in response to more progression to it west and north. Eventually the features move. The eastern nose of the high pressure area will play a part in giving us fair weather from today through Tuesday, after which it will give way to a northeastward-drifting low pressure area that will increase our clouds and wet weather chances as we head through midweek. I don’t think it will be in a hurry to get all that wet here, though, as the low from the south will be broad and disorganized with no super organized areas of rainfall, instead a more broken rainfall pattern.<\/p>\n\n\n\n

DAYS 6-10 (MAY 16-20)<\/p>\n\n\n\n
Pattern shift is slow, still in the hybrid block – low pressure not completely connected to the jet stream which becomes more progressive overall. The low pressure area that dominates the eastern US looks weaker than the one associated with the recent omega pattern. This pattern for us would deliver a southerly air flow shifting more westerly with time, but occasional shower chances with fair weather being dominant the majority of the time. Temperatures, while variable, would average near to slightly above normal.<\/p>\n\n\n\n
DAYS 11-15 (MAY 21-25)<\/p>\n\n\n\n
Heading into late month, the strongest indications are for a progressive pattern – general west to east flow – but with a mean trough in eastern Canada and the northeastern US, making us more susceptible to a shot or two of cool Canadian air with temperatures near to below normal. Overall pattern looks drier.<\/p>\n","protected":false},"excerpt":{"rendered":"
