Weather Underground Forecast for Monday, October 17, 2011.
Wet and windy weather will continue in parts of the Great Lakes and the Northeast on Monday as deep low pressure lingers over eastern Canada. West winds gusting up to 50 mph are expected in the Lower Great Lakes and parts of the Northeast and may result in downed tree limbs and scattered power outages. Meanwhile, an associated low pressure system will lift northeastward into the Northeast with a few light showers. Significant precipitation is not expected with this system due to a lack of moisture.
In the South, deep tropical moisture streaming ahead of an area of low pressure moving northeastward over the eastern Gulf of Mexico will fuel more active weather in central and southern Florida on Monday and Tuesday. This moisture combined with a stalled frontal boundary in southern Florida will trigger more showers with embedded thunderstorms through the afternoon. Locally heavy rainfall with rain amounts of 2 to 4 inches will create chances of minor urban and street flooding mainly over southern Florida. In addition to heavy rainfall, strong east winds existed across the region and lead to a high risk of rip currents along the Atlantic coast beaches.
Elsewhere, a fast moving disturbance from the Northwest will drop southeastward across the Intermountain West and the Central Rockies with valley showers and high elevation snow. Total snow accumulations of 3 to 6 inches are expected over the higher elevations by Monday afternoon. The system should reach the Central Plains with showers and thunderstorms during the latter half of the day. Temperatures in the Lower 48 states Sunday have ranged from a morning low of 21 degrees at Havre, Mont. to a high of 93 degrees at Imperial, Calif.
