Temperatures will be well above-normal in the central US during the next couple of days and this warm-up will extend to the eastern US this Friday and Saturday. However, a pattern change to colder-than-normal weather begins next week in the central and eastern US and this change looks like it will have some staying power. Numerous teleconnection indices point to a significant change in the overall pattern that indeed could last into March and recurring stratospheric warming supports the idea. As far as storm threats are concerned, signs are increasing for low pressure to push into the Mid-Atlantic region early next week on the front-end of this pattern transition. While there will be no cold air established on the front-end, it is possible that cold air can get wrapped into the system depending on its track so accumulating snow cannot be ruled out.
Remainder of this week
Temperatures will climb to well above-normal levels across much of the central US during the next couple of days on the back side of high pressure and this mild air mass will shift to the eastern states for Friday and Saturday. In fact, temperatures on Saturday afternoon can peak in the upper 50’s-to-middle 60’s in the DC-to-Philly-to-NYC corridor ahead of an incoming cold front. However, that cold frontal passage will begin a transition to colder weather conditions in much of the eastern half of the nation that may very well have some staying power.
