Yesterday the weather gods provided us with a gorgeous St. Patrick’s Day, with sunny skies and temperatures just above 60°F. The above-average warmth — normal highs are in the mid-40°Fs this time of year — will continue tomorrow, with temperatures pushing into the upper 60°Fs. These highs are due to strong warm air advection, aided by a low-level jet in front of an approaching cold front. Unfortunately, our taste of spring will not last, as the cold front will pass through early tomorrow evening, ushering in cooler, more seasonal air for the weekend. Associated with the cold front passage, we will see gusty winds tomorrow afternoon and evening. A high pressure system will keep our weekend dry before the next low moves in on Monday for the start of spring break.

The high pressure system that has brought us sunny, dry weather for the last week has finally moved off the coast, allowing a sequence of storms to impact our region over the next few days. The first system comes through today, bringing heavy rain and blustery conditions. The rain should taper off by the evening, but could be quite heavy at times this morning and this afternoon. We should receive 1.5–2 inches of rain. As for the wind, the southeast winds of the morning will weaken and shift as the low passes in the afternoon, before shifting to strong northwesterlies on the backside of the low. Gusts of up to 55 mph are possible tonight. Saturday will be mostly quiet before a shortwave trough brings a chance of snow showers on Sunday morning. The next major system moves in on Monday; right now it looks like it will be mostly rain, but some sleet and freezing rain could be mixed in.

For the last several days, we have been experiencing temperatures in the 50°Fs, tricking us into thinking that spring has arrived. Yesterday it reached 59°F at Logan Airport, just shy of the 61°F record high. Warm temperatures will persist today thanks to a high pressure system in the Atlantic that is spinning warm air our way. However, the rest of the weekend will feature a return to normal conditions, with high temperatures in the upper 30°Fs. A cold front will pass through tonight, but a lack of moisture associated with it means any precipitation will be minimal. Saturday and Sunday will be partly cloudy with blustery conditions that will make it feel quite cold compared with yesterday and today, especially on Saturday, when gusts of up to 45 mph are possible. For our day off on Monday for President’s Day, a low pressure system will bring the possibility of a wintry mix of precipitation.

After a seemingly endless string of strong winter storms during January and the first week of February, the quiet weather this past week has been a welcome reprieve. January was a snowier- and wetter-than-average month for Boston, with 38.3 inches of snow and 4.57 inches of total precipitation (liquid equivalent), compared with normal values of 13.5 inches and 3.92 inches, respectively. The 38.3 inches of snow fell just short of the January record, which was 43.3 inches in 2005. Thankfully for those who are weary of shoveling, the quiet weather of the past week should continue through the middle of next week. There are a couple of clipper systems lined up to move rapidly through New England over the weekend, but their relatively weak strength and lack of moisture will keep any precipitation limited to a few scattered snow showers.

Yesterday’s storm system took a track similar to that of last week’s blizzard, but wasn’t accompanied by nearly as much cold air. Thus, we received the dreaded “wintry mix”; snow followed by sleet, freezing rain and rain, instead of all snow. Most of that should be out of the region today, leaving us with relatively dry conditions until the next storm system comes Thursday night into Friday. Different models have that system tracking differently, either eastward from the Ohio Valley or coming up the coast. In Cambridge, most, if not all, the precipitation associated with it should be snow (possibly around 6 inches). Following this, a high pressure will move in giving us a sunny but frigid weekend, with highs in the teens and lows in the single digits. Bundle up!

According to the National Weather Service, this December was the 9th snowiest December on record for Boston, MA, with 22 inches of snow recorded. A significant portion of that (18.2 inches) was due to a single storm, the December 26–27 storm. This snowstorm tied for the 10th greatest snowstorm total for Boston, and was also the greatest 24 hour December snowfall amount. We won’t need to wait long for our next chance at significant snowfall. Following a high pressure system that will have control over the area until Friday, the forecast models are predicting the development of a strong coastal or offshore low pressure system that would impact our area Friday–Saturday. There is still much uncertainty surrounding this system, both in terms of the timing and track (which of course affects the snowfall total), but there is a good likelihood for precipitation in our region.

Yesterday’s sunny skies and seasonal temperatures will give way today and tomorrow to increasing clouds and warmer than average temperatures ahead of an approaching low pressure systems. The models are predicting a secondary low (associated with a low pressure in Ontario) to form in central New York and affect our region on Wednesday.

The gorgeous weather this past weekend was displaced by a weak cold front that crossed the area Sunday and Monday. Low level easterly flow yesterday brought moisture off of the Atlantic, causing there to be low clouds throughout the day.

Fall weather in New England is characterized by a great deal of variability in the day to day weather, particularly the temperature. The temperature oscillates back and forth between warm and cold, while overall trending colder as we move towards winter. This will be especially apparent over the next couple of days. A cold frontal passage last night brought dry, cold air into the region, making today’s high 5–10°F below normal. Breezy conditions out of the northwest will make it feel even colder, so it is definitely a day to break out a jacket. The dry, clear conditions mean the temperature could drop quite a bit over night into the lower to mid 30s °F . Over the weekend, partial sunshine and warm air advection will moderate the temperatures, before we enter a few days of above average temperatures (upper 60s °F) at the beginning of next week. The weekend should be mostly rain free, with the exception a chance of showers on Sunday afternoon.

After a couple of gray, rainy days in the early part of this week, more pleasant weather will be in store for us this weekend. Today will be mostly sunny with warm temperatures, but could be quite breezy ahead of an approaching cold front. There is not much moisture associated with this front, so there are no showers expected as it passes on Friday night, but it will bring cooler temperatures and increasing clouds. High pressure will then take over for the rest of the weekend, with temperatures in the low to mid 60°Fs and sunny skies expected. With the dry airmass and mostly clear conditions on Saturday night, the temperatures could be cold enough to have the first frost of the season. As the high pressure moves offshore on Monday, southwest winds will bring milder temperatures, making for a pleasant Columbus Day.
