Metro Boston, north shore and metro west: January has seen big fluctuations in temperatures with a bitter cold beginning of the month, followed by a mid month thaw and now back to the frigid cold these last few days. For the first three weeks of the month, as reported at Logan Airport in east Boston, we are averaging just about normal for the month with an average temperature of 29.5 degrees. The average highs have been near 37 with the lows averaging 22. Both of these numbers represent just where we should be for this time of year. But, very few days have actually been around the norm. For example, there were four consecutive days with high temperatures of 50 degrees or higher, 11th through the 14th, and another three days of 40 degrees or above. On the flip side, two days we failed to see our highs get out of the teens, another seven under 30 degrees and 6 nights when the mercury slipped under 10. Many interior communities had low temperatures fall below zero several times this month.
As for precipitation we are ahead of the normal pace through yesterday. About 21 inches of snow has fallen at Logan Airport, many suburbs recording more than this, which is well above average so far this month. Temperature and precipitation information courtesy of the National Weather Service.
More cold and some snow is in the forecast for the upcoming days. The bigger story will be the cold, except briefly milder on Saturday, otherwise it appears we are headed for more much below normal cold into next week.
Thursday morning temperatures settled to a few degrees on either side of zero through the area. Through mid morning there has not been much recovery, many now only in the low teens, with highs this afternoon falling short of 20.
A disturbance is sliding out to sea south of New England today and will have little impact on the area other than to spread some clouds our way. Once this system passes into the open waters of the Atlantic more cold air will follow for tonight and Friday.
A vigorous storm system in south central Ontario will move northeastward and drive another cold front through here late Saturday. Gusty southwest winds ahead of the approaching front pushes temperatures into the 30s with the threat of snow showers, possibly a few squalls, during the day on Saturday and into the evening. Behind this front more frigid air returns for Sunday.
A quick moving disturbance approaches later Sunday and may bring a period of snow at night and early Monday.
