Our weekend will wrap up on a pleasant note. Though clouds will be on the increase, temperatures will rise to much warmer than normal levels by early-December standards. Highs today will top out in the lower to middle 50s with increasing cloudiness.
Those clouds will eventually give way to rain during the overnight hours. A few sprinkles are possible this evening, but it’s not until midnight and into the predawn hours that the more concentrated rain will arrive.
Most of central Indiana can expect rainfall totals between 0.50″ and 1.00″ Monday. The steady rain Monday morning will taper to showers during the afternoon hours.
Colder air will pour into the state Monday night and gusty northwest winds. This cold air mass will eventually “catch up” with the moisture to our southeast and lead to a flip to snow for places from central and eastern KY into the Appalachians Tuesday. Meanwhile, lake effect snow showers will develop across northeast Indiana. For the most part, despite some light snow showers Tuesday morning, central Indiana shouldn’t expect anything “exciting” in the winter weather department.
High pressure will settle overhead through the midweek stretch with sunshine returning along with seasonably cold conditions.
Thereafter, a developing storm system in the Gulf of Mexico will lead to an active close to the week. Low pressure will form in the central Gulf Friday afternoon before tracking up along the Appalachian chain into the weekend. With a lack of cold air and retreating high (orientation of the cold air supply/ high pressure system is critical this time of year), this should be another mostly wet and not white weather maker.
Cold air will eventually wrap into the system from the west late in the weekend and could lead to precipitation ending as wet snow, but this idea is far from being “etched in stone.”
Video update will come a bit later with fresh 12z thoughts, along with a look-ahead to Christmas. Make it a great Sunday, friends!
