Heading into the final week of January we can look to more abnormally cold temperatures but a mainly dry week. So far the month of January has provided us with a cold start and most recently a cold trend as we head toward the end of the month. Sandwiched in between was a decent period of thawing temperatures which kept the overall mean temperature for the month from being substantially colder than average.
We mentioned the other day systems are moving at a rapid pace. A disturbance in the western Great Lakes at midday Sunday will be positioned near Montreal Monday morning quickly moving into New Brunswick by midnight. With this system moving to our north we will once again develop a strong southwesterly flow later tonight and Monday which in turn drives temperatures into the 30s on Monday. As a matter of fact the temperatures will begin their ascent late tonight as we reach our lows before midnight. A few snow showers are possible during Monday, before another cold front blasts through in the afternoon. Once that happens the temperatures crash overnight and Tuesday morning you are going to wake up with temperatures in the single digits throughout the area.
Tuesday is expected to be similar to what we experienced on Sunday. That is to say another cold and blustery day with a good amount of sunshine. Another very cold night follows.
An ocean storm misses us well to our southeast during mid week. A dominant high pressure area will eat up most of the eastern half of the country through the week keeping us dry and abnormally cold. Very cold air will push all the way into the deep South as well.
Late in the week another cold front approaches. Ahead of the front temperatures begin to moderate back to near seasonal levels by Friday.
