Hydromet Outlook through June 4th
High pressure building over the Northeast this weekend will very slowly retreat to our east during the week of May 24th. There will be a developing ocean storm well south of the region and at this time it is forecast to remain well offshore. Little in the way of significant precipitation is forecast (greater than 0.50 inches) and the prevailing winds should be from the south and west, other than some periodic sea breezes along the immediate coast.

During week two - the flow regime will switch bringing cooler than normal temperatures
but only near normal precipitation. Around Memorial Day, the combination of high pressure building south from Canada and the expected development of a storm system near the Canadian Maritimes may produce a period of rain over Maine and a period of northeast winds. A second system may produce some rain and a brief bout of east or northeast flow in the Wednesday-Thursday time frame to be followed by another high pressure system from Canada.
