This will serve to shift winds and bring a brief end to rain though showers will continue across the north as upper level cold pool(a region of relatively cold air) lingers thru the day. With winds beginning to increase in the lower levels expect most of the marine layer will be more in the form of low stratus as opposed to fog especially with surface low deepening to the north of Maine.Īs surface low begins to wrap itself up late tonight occlusion will move thru the FA between 09-15z. Expect that all areas will see rain and embedded thunder after midnight, along with fog. Have backed off on probability of precipitation across the northwest as H5 low will take it's sweet time ejecting to the east. Have retained isolated thunder mention this afternoon into this evening across the north.Īrea of storms moving north out of New England into southern Quebec will very very slowly push east toward the CWA (County Warning Area) this evening. Convective showers have developed along this boundary and moving north this afternoon though they are not tall enuf to produce lightning. This can be seen reflected in surface analysis as well as cu field developing under the high clouds. Early morning low stratus and fog likely created a differential heating boundary across the north with Storm Prediction Center meso page indicated 500 J/kg to the north of a Houlton to Katahdin line. Previous discussion: Upper level low looks to be located near Buffalo NY Otherwise, only minor tweaks to account for the current and expected conditions.
Did lower the Probability of Precipitation and associated Quantitative Precipitation Forecast for the next few hours based on the latest radar trends. The highest PoPs/greatest Quantitative Precipitation Forecast are still expected to be north of Bangor. This will change overnight as rain overspreads the region with embedded thunder still possible. A warm front will lift north through the area Sunday.ĩ:12pm Update: Area radars show very little in the way of returns across the FA attm. High pressure will build across the region Thursday into Saturday. A cold front will cross the region Wednesday. Low pressure will move north of the area overnight.
