The antithesis of last week’s general weather pattern will invade the Capital Region over the next 24 to 48 hours. The cold high pressure area that dominated the weather the past few days was off of the eastern New England coast this morning. Over time, an increasing southerly flow of milder air will be transported into the Capital Region and vicinity.
An area of low pressure, exiting the Four Corners region early Friday morning, will move quickly to the central Plains tonight, the upper Great Lakes by Saturday morning, and to the vicinity of the tip of James Bay in Canada, by Saturday evening. The low pressure system’s warm front should sweep through the area Saturday morning, allowing for warmer temperatures, of about 10 to 20 degrees above normal, to take hold for Saturday. In addition, some periods of moderate to heavy rainfall are forecast to occur overnight tonight, through Saturday night.
Area rivers and waterways will swell as the rainfall occurs over frozen ground. This will create excessive runoff, as the rain will unable to efficiently soak into the ground. Due to the recent cold snap, extensive ice formation has occurred on area rivers as well. The threat for flooding as result of ice jamming will be elevated during the day on Saturday, lasting through Sunday morning.
Of concern as well will be areas of patchy, dense fog. This is especially true for those areas that still have a sufficient amount of snow on the ground. The time frame for the dense fog looks to be overnight Friday, through Saturday morning.
A flood watch has been issued by the National Weather Service in Albany, NY, for the entire Capital Region and vicinity. The watch goes into effect on Saturday afternoon and lasts through Sunday afternoon. A flood watch is issued by the National Weather Service when flooding is possible. A warning is issued when flooding is imminent or occurring, and immediate action should be taken. Those with interests in flood prone areas should take precautions now to protect life and property in the event that flooding occurs.
Those experiencing flooding conditions should move to higher ground immediately. Remember, flash flooding can occur suddenly, and with little or no advance warning. Ice jams can cause water back-ups that can flood areas in the vicinity of the jam quickly. Upon breakage of the jam, the sudden surge of water downstream can also create flooding quickly in downstream areas.
