High pressure controls New England this week, bringing lovely weather. In a high pressure system, air descends from above; since the cold air high in the atmosphere cannot hold very much water vapor, this descending air is dry and causes clear, sunny conditions. Due to the lack of clouds, the surface radiatively cools very efficiently at night, leading to cool mornings and a large diurnal temperature gradient. Low pressure systems have the opposite effect; moist surface air convects upwards, condensing and forming clouds at the altitude where the temperature is too low to hold excess water vapor. At least for this week, we shouldn’t see those sorts of clouds!

After some spring-like weather earlier this week, temperatures have cooled down and will remain slightly below average for the foreseeable future. While in the past Boston has recorded highs in March above 70°F, the mean high temperature is 46°F. This weekend will bring temperatures around freezing, with scattered clouds and chances of precipitation.

NOAA and FEMA mark National Severe Weather Preparedness Week from March 3 to March 9. Prepare an emergency supply kit, sign up for severe weather alerts, and share warnings and plans with your peers; it could save your life! Primary threats in Massachusetts include floods, severe thunderstorms, blizzards, hurricanes, and tornadoes. For more information, visit the National Weather Service website.

A few days of relative warmth and sun started melting the snow that piled up from last weekend’s blizzard. However, winter weather will return by the end of this weekend, with light snowfall possible on Saturday and an Arctic air mass moving in on Saturday night. On Saturday, expect temperatures around freezing, with cloudy skies and a chance of rain and snow in the afternoon and evening. Sunday and Monday will bring crisp, clear mornings with windchill in the single digits. Only 14 more days until meteorological spring begins!

A series of unsettled weather will move through New England this weekend, bringing alternating periods of precipitation and warmth. Today and tomorrow will remain cold; however, expect temperatures to warm up by early next week.

After a lovely weekend more reminiscent of September than late fall, temperatures in Cambridge will cool down after a cold front passes through this morning. For the rest of the week, high pressure will dominate, bringing mostly clear skies and temperatures in the 35-45°F range.

The largest Atlantic hurricane in over 25 years made landfall on the New Jersey coast on Monday evening. High winds from Sandy have downed power lines and trees over a vast expanse of the U.S., from Florida all the way to Maine. Blizzard warnings are in effect over parts of the Appalachians, where a cold Arctic air mass clashed with the moisture-laden air rotated counter-clockwise from the Atlantic Ocean. Peak tide levels and coastal flooding may overtop that observed in New York during Hurricane Irene last year.

The next few days in Cambridge will display lovely fall weather, with clear skies and temperatures mainly in the 50°s F. Autumn foliage is in full color, so be sure to look outside. This weekend will bring another low pressure system through the area with its corresponding precipitation and wind, but models so far show a quick passage; most likely for at least part of the weekend it will not rain.

As a low pressure system moves over the region, Cambridge will experience damp, cloudy conditions with intermittent precipitation. Temperatures will remain seasonable, with highs in the 60°s for the next several days.
