The winds and rains associated with the former hurricane, now post-tropical storm, Sandy, are lessening in strength and intensity across the Capital Region this morning. High wind warnings, previously in effect, have been downgraded to wind advisories. Flood watches which were in effect for the entire region have been discontinued. However, flood warnings remain in effect for portions of the Hudson River, from Albany and points south due to tidal influences and remaining storm surge from Sandy, acting in tandem to keep water levels elevated.
The low pressure area that was Sandy is currently traversing southern Pennsylvania. Movement speed has become slower. The storm is expected to continue tracking to the west, and eventually the northwest as it moves around the periphery of an upper level ridge of high pressure located over far northeastern Canada. This trend should put the low pressure area in the vicinity of the western Pennsylvania and southwestern New York border by Wednesday morning, and then over the Saint Lawrence Valley in Canada by Thursday morning.
Building high pressure to our south, and the departing low pressure area to our north, will provide a steepening pressure gradient across the region by week’s end. In addition, weaker upper level disturbances will pass through the area, bringing the threat for shower activity from time to time. As the week draws to a close, cooler air will be filtering southward from Canada, on the back side of the remnant low pressure that was Sandy.
In short, temperatures look to start the forecast period above normal, trending to near normal by the end of the period. Precipitation amounts look to remain near normal through the period.
