Weekly Outlook: October 12-18, 2020

Some much-needed rainfall is finally on the way, but we need a lot more.

The remains of Hurricane Delta will move into the Mid-Atlantic states today, bringing that region some more heavy rainfall. Some of that rain will get into southern New England today, but it doesn’t look like it will make too much progress northward, thanks to high pressure that will be slow to move out. Right out, it looks like most of the rain today will be south of a line that stretches from Hartford to Providence to Plymouth, or roughly south of Route 44. A few showers may get farther north, but the bulk of the rainfall should stay south during the daytime. With the high to the northeast and low pressure to the southeast, we’ll have brisk northeast winds resulting in a rather cool day across the region, with temperatures likely staying in the 50s for most of us.

As low pressure gets a little closer tonight and a cold front starts to approach from the west, rainfall should become more widespread across the region. Some of the rain may be heavy, and it may actually bring down some warmer air from aloft, allowing temperatures to rise a few degrees. The rain continues into Tuesday, which should be a bit milder, ending from west to east during the afternoon as the cold front moves across the region.

High pressure builds in for Wednesday and Thursday, bringing some sunshine and milder weather back in. However, our dry and mild weather will be short-lived. Another cold front approaches on Friday, with another round of showers expected. Some of the models try to develop an area of low pressure along this front which would bring some heavier rain into the region, but we’re skeptical of that scenario at this point. Since the drought began in the Spring, we’ve seen numerous model forecasts for a decent amount of rain several days out that fizzle as it gets closer. Until we see something to change our mind, we’ll continue to lean towards lighter amounts of rain. (Even the rain for today/tomorrow was forecast to be much heavier by the models just a day or two ago) While we’re leaning dry, we are mindful of the fact that more than one model is going for the rain to last through Saturday and into early Sunday. In fact, one of the models actually has the rain change to snow across the mountains of northern New England this weekend as colder air moves in. Obviously, we should have much more clarity on the weekend forecast when we issue our Weekend Outlook Thursday afternoon, but we just wanted to warn you up front that although our forecast right now shows a decent weekend, that is subject to change.
