DISCUSSION
KEY MESSAGE 1...Above normal temperatures are expected through this weekend with shower chances returning later Wednesday afternoon into Thursday.
KEY MESSAGE 1 DESCRIPTION... A broad upper level ridge is expected to remain in place across the Hudson Bay into eastern Canada and the northeast US this week, leading to persistent above normal temperatures with daytime highs generally in the upper 70s to 80s forecast through this weekend. Dew points will generally remain comfortable in the 50s, lessening heat related impacts. Heat risk is generally in the minor category, suggesting any heat related issues will be mostly confined to vulnerable populations. The warmest day closer to the Downeast coast will be Tuesday before winds become lighter and out of the south with the daily sea breeze.
A weak disturbance cutting underneath the ridge near the US- Canada border will provide moisture for cloud cover and showers late Wednesday into early Thursday. The greatest chances will be across western areas, where a rumble of thunder is possible. The combination of poor mid level lapse rates and minimal instability with MLCAPEs less than 500 j/kg will preclude much of a thunder risk farther east.
