Active Week Ahead
Posted by Trevor Cole in Daily Weather Updates on 29-11-2009
The upcoming week will feature several chances for precipitation (both rain and snow), as well as a roller-coaster ride of temperatures.
Mon
A fast-moving storm system will continue to slide northeast, helping to push a cold front through the area(which will bring cooler air and clearing skies). Most of the shower activity will end by noon (with the exception of scattered afternoon activity). Temps will remain cool given the thick cloud cover and spotty showers.
Tue
High pressure will gain control of the Ohio Valley briefly for Tuesday. Expect partly cloudy skies and highs in the lower 50s to be the norm, which is certainly a tease for what is to come!
Wed-Thu
High pressure will continue to move east on Wednesday, ahead of a developing low pressure system sliding north out of the Gulf of Mexico. While this storm has been poorly modeled by the various forecasting tools/models over the past several days, an increasing amount of agreement has been occuring over the last couple runs (models showing a similar output). At this point in time, it appears that the low pressure center will track very close (or right over) the tri-state, resulting in a rain event (possibly heavy). Given the track, we will be in or very close to the warm sector, which will provide us with milder temps (highs in the upper 40s/lower 50s). As the system really begins to bomb out to our north on Thursday, much colder air will spill into the tri-state, allowing any remaining moisture to fall in the form of snow. Some of the models are showing a quick thumping of snow right behind the cold front, possibly accumulating up to an inch or two. Given the warm ground/marginal surface temps, any accumulation would be confined to grassy/metal surfaces, as well as bridges/overpasses. However, as temps plummet Thu night (low/mid 20s), any remaining water/slush would easily re-freeze, especially on untreated surfaces. Temps don’t rebound much at all by the time Friday rolls around, as highs will only make it into the middle 30s!
Sat-Sun
Temperatures will begin to moderate a bit for Saturday as high pressure once again takes a brief term of control. Expect highs to top out in the lower 40s along with partly cloudy skies. For Sunday, clouds will once again be on the increase as another storm system closes in. Rain looks to develop during the pre-dawn hours, continuing through the rest of the day and into early next week. Highs will once again only make it into the 40s, so if the system were to pan out in the fashion that today’s models are showing, it will definately be a chilly rain. Given the fact that said storm is about a week away, much can change. Some models are showing a snowstorm, while a majority are showing rain (possibly heavy), ending as snow. I will have a much better idea of the storm’s output by the middle/end of this work-week!
