The National Weather Service in Taunton has declared this week as severe weather preparedness week in southern New England, and will be issuing informational statements each day of this week on their website. On that note, it is important to be aware of severe weather in the Boston area, which does occur in the summer months. Commonly, lighting, hail, tornadoes, and flash flooding are associated with severe weather. On days in which conditions are favorable for the development of severe thunderstorms or tornadoes, the Storm Prediction Center in Norman, OK issues a watch.

Boston experienced unusually warm weather this week, most notably on Wednesday when the record high of 86°F set in 1991 was smashed by a high of 90°F. Expect more seasonable weather to return for the weekend, which will be dry except for a chance of rain today.

The temperature again today will soar to pleasantly warm levels, thanks to the absence of any major cloud cover. A combination of sunshine and a southwesterly flow will create an even warmer day on Saturday, with the high reaching 70°F (21°C). This type of setup is often seen during the spring months in Boston, where a high pressure center off the coast of the Carolinas sets up a flow from the southwest that draws much warmer air into our region. An approaching cold front will bring cloud cover on Sunday and not allow the temperature to become as warm.

Early Sunday morning marks the beginning of Daylight Saving Time (not Daylight “Savings” Time), when we move our clocks one hour forward. Eastern Standard Time (EST), five hours behind Greenwich Mean Time (GMT), gives way to Eastern Daylight Time (EDT), four hours behind GMT. The good news is that the sun will set an hour later, but at the price of one hour less of sleep on Saturday night.

High pressure remains in control over the eastern part of the country, giving us a period of quiet weather through the end of the weekend. Plenty of sunshine will be available, giving some of the snow in the area a chance to melt, although this might be bad news for those who enjoy skiing and snowboarding. A “heat wave” slides in on Friday, with a high of 47°F, which is over 10°F above average for this time of year. Long range forecasts show the possibility of a winter storm Monday and Tuesday, but at this point the weather then is rather uncertain.

Do you like cold, rain, and wind? You’re in luck! An intense low pressure system moving through the Great Lakes will trigger a secondary storm that will affect our region tomorrow. Precipitation may start out as sleet or snow due to the cold air currently in place, but will soon change over to rain as warm air is advected in the area. Rain may be heavy at times during the day tomorrow. The wind will also be an issue tomorrow and Thursday, with very blustery conditions much like what we have been seeing recently. After the storm exits, cold air from Canada digs into the region, with lows in the 20s°F and highs in the 30s°F Friday and Saturday.

High pressure builds into the area today, providing light winds and a sunny sky and letting meteorologists let down their guard for a few days. Light winds and a lack of clouds is a win-win combination for winter cold at night, since these are the circumstances that allow the ground to radiate heat efficiently to space once the sun goes down.

A tight pressure gradient will be in place this weekend between a high pressure system off the coast of Nova Scotia and a strong low pressure system over southwestern Ontario. This will cause a strong flow from the southwest, bringing hot, steamy air to our region. High temperatures on Saturday will top out around 69°F (21°C), well above average, so no need to cover up your Halloween costume. The remainder of the weekend will be dry with the next chance for rain on Sunday night.

As winter approaches, the days and nights grow colder and colder as the sun’s position above the horizon gets lower and lower. At night, the temperature is also dependent on the presence of clouds. On a clear night, radiation from the earth’s surface escapes efficiently to space. On a cloudy night, the clouds act as a blanket that traps radiation. Tonight, as the clouds clear out, temperatures will plummet into the upper 30s°F, the coldest night we have seen yet this fall. Temperatures this week will be generally colder than average, as cold air from the north dominates our region.

Many people are often foiled by the assumption that today’s weather will be the same as yesterday’s weather, finding themselves wearing shorts when things suddenly take a turn for the cooler side. Such quickly changing weather is a consequence of living in the midlatitudes, where the circulation pattern is dominated by what meteorologists call eddies.
