Warm vs. Cold
Warm vs. Cold
As is frequent this time of the year, there can be a considerable difference in temperature over a short distance, i.e. a large temperature gradient. Fronts are usually responsible for these gradients, while the fronts are associated with low-pressure systems. One such low-pressure system located over the northern Great Lakes region yesterday sent a cold front plunging down into the Plains and Midwest. On the east side of the front, temperatures were generally in the 50s and 60s°F (10–20°C), whereas on the back side temperatures plunged as low as -30°F (-35°C)!
We won’t be experiencing temperatures as low as that anytime soon (Boston’s all-time record low is -18°F), as the airmass will moderate substantially before reaching our region. Look for rain and breezy conditions to develop early this morning and continue into the late morning, with perhaps some sunshine before the sun sets. We will have a pleasant day on Thursday, followed by another system moving through for Friday. The good news is that the weekend looks to be a bargain for this time of the year.
Thursday: Sunny with increasing clouds during the evening. Highs near 40°F (4°C). Lows in the upper 20s°F (-2°C).
Friday: A mix of snow and rain in the morning, changing to all rain by noon. Highs in the lower 40s°F (5°C). Lows in the mid 30s°F (2°C).
This weekend: Partly sunny and pleasant. Highs in the mid 40s°F (7°C). Lows in the upper 20s°F (-2°C).
