Boston Weather: 47.0°F | Light Rain

Weather: Warm Welcome

By Gerard Roe
Staff Meteorologist

After the recent bitterly cold weather, some welcome relief is in store, if only briefly: We are in for the usual squeeze play of a developing cyclone running westward toward a high pressure centered just off shore. This means strong pressure gradients and therefore high winds. This particular system has a long southwesterly fetch to it, bringing up warm air out of the gulf. We may even touch 50F (10C) as temperatures rapidly climb after the warm front passes through mid-morning. A mid-level atmospheric wave will produce some overnight rain that will die off early Thursday morning. Thursday itself will turn a little cooler, and by Friday we will be back to the more seasonable mid 30s (2C) as the winds shift round to northerly behind the departing storm.

In the outlook, Saturday night may see a coastal development, bringing more precipitation across the region. However, rain is still more likely than snow, which will lend no comfort to frustrated skiers.

Today: Starting off clear. Strong and warm southwesterly winds. High clouds developing during afternoon. High 49F (9C).

Tonight: Moderate rain spreading in from the west around midnight. Totals of around a quarter of an inch. Continued warm. Low 40F (4C).

Tomorrow: Any lingering drizzle dying out during the morning. Becoming sunny. A little cooler during the day. High 42F (6C). A comparatively chilly night with a low of 26F (-3C).

Friday: Cooler, but fair. High around 35F (2C). Low about 25F (-3C).
