Temperatures are going to flip flop over the next few days. It will get colder, then briefly milder, followed by much colder air toward the end of the weekend lasting into next week.
A strong cold front has moved offshore and will introduce much colder air into southern New England. In contrast to Thursdays above normal temperatures and light winds we can expect stinging cold on Friday as high temperatures remain in the mid to upper 20s and winds howl out of the northwest. The combination will bring us wind chill values in the single digits to teens throughout the day, even though a good amount of sunshine will prevail. Clouds will be on the increase at night, with low temperatures falling to around 20 degrees. It remains breezy, but the winds will start to shift to the southwest overnight which is a sign that temperatures become milder.
On Saturday, a ridge of high pressure will slide offshore and a southwest wind sets up over the area. After Fridays wake up call to winter, we go back to above normal temperatures Saturday, with highs back into the 40s. However, winds are expected to get quite feisty out of the southwest, perhaps gusting to over 30 mph. As a result the wind chill will make it feel much cooler from the actual temperature. Lots of clouds will be around through the overnight, with a few periods of sunshine during Saturday. Lows at night around 32 degrees.
Sunday brings about big changes again. An arctic front will be charging toward the region and push through here by midday. Much colder air and a continuation of windy conditions will be the theme later Sunday and Sunday night. Highs should top out around 40, perhaps falling through the 30s during the afternoon. The mercury falls back to near 20 Sunday night. Winds will be brisk out of the northwest.
Monday and Tuesday will not only be much colder, but a threat of snow will be present as an ocean storm develops off the North Carolina Coast and moves northeastward. How much intensification and how close this storm comes to southern New England remains to be seen this far out. It certainly bears close monitoring over the weekend to determine what impacts this storm may have on the local area. Keep in mind this storm has not even taken shape yet and will not do so for several days, so the margin for error at this point is considerable. More on this as the weekend unfolds. As of now it appears Monday starts out sunny, followed by increasing clouds. Mostly cloudy at night into Tuesday. Highs both days about 25 degrees, with overnight lows 10 to 15.
