Storm threatens Ohio Valley/Northeast Thursday

2:30 P.M. ET 11/3/2004


Kevin Roth, Senior Meteorologist, The Weather Channel





A storm system lifting into the eastern Great Lakes should spread a shield of clouds and rain from the Ohio Valley through western New England Thursday. Rainfall could be locally heavy – possibly 1 or 2 inches – from eastern Virginia north to southern New York state. Cloudiness and rainfall should hold temperatures mainly in the 40s and 50s throughout the Northeast Thursday. Chilly air moves in on gusty winds behind the storm for Friday. Snow or mixed snow and rain showers are possible across western New York.



Low pressure traverses the Ohio Valley during the day Thursday. Rain, showers and a few thunderstorms should accompany the storm as it moves through. In general, rainfall should average around ½ inch, with local amounts in excess of one inch possible, across the Ohio Valley. The system blows out of the area Thursday night on gusty northerly winds. Some rain and snow showers will be possible around the Great Lakes Thursday night and Friday morning. Milder weather should move into the region for the weekend.



A ridge of high pressure has been dominating the weather across much of the South since the middle of October with warm temperatures. A cold front should knock that ridge out to sea and replace it with more seasonal readings into this weekend. A band of showers and thunderstorms, some with locally heavy rain, should occur along the cold front as it marches across the Carolinas Thursday. Florida should continue to bask in relative warmth Thursday before the front reaches that area Friday.



An upper level low will spin across central California bringing some snow to the Sierra-Nevada mountains Thursday. Lower elevations near the mountains should see a few scattered showers. This upper level low is going to be slow to move and could still be in the Golden State Friday and Saturday. That is good news for the ski resorts and the water supplies in the lower elevations. The Northwest should remain dry into the weekend.



There is no appreciable tropical activity in any ocean basin so I will not make any tropical posts today.
