A Wind-Swept Heavy Rain Expected Thursday Night Until Friday Night

For This Afternoon: A west to northwest wind flow over the region will produce a mixture of sunshine and clouds this afternoon. In addition, a couple of snow showers are possible. Temperatures will be between 35 and 40 Degrees. Winds will be West at 10 to 20 mph with gusts to 30 mph. Tonight Through Tuesday: An area of high pressure will gradually build into the region tonight and Tuesday. Skies will start out tonight partly cloudy, but will become clear after midnight. Low temperatures will be between 20 and 25 Degrees. Winds will be Northwest at 10 to 20 mph. Tuesday is expected to be a sunny day with high temperatures between 35 and 40 Degrees. Winds will be Northwest at 8 to 16 mph. Wednesday: That high pressure system will continue to control the weather during Wednesday with sunny to partly sunny skies expected. High temperatures will be between 35 and 40 Degrees. Winds will be Northwest at 5 to 10 mph. Thursday: Even though Thursday will be dry across the region, clouds will begin to increase as a strong low pressure system moves across the Great Lakes and Ohio Valley region. High temperatures will be between 40 and 45 Degrees. A Wind-Swept Heavy Rain Is Expected From Thursday Night Through Friday Until Friday Evening: A strong storm system is expected to track from the eastern Ohio Valley on Thursday evening to western New York State by Friday morning. This storm system is then anticipated to move into Quebec province during Friday afternoon and evening. Given the expected storm track that’ll be to the west of our area, it looks very likely that we’ll be on the mild side of the storm system. Because of this, it appears that a majority of the precipitation type with this storm will be in the form of rain. In addition, there is likely to be quite a bit in the way of wind with this storm system, both on the front side and the back side. So, a wind-swept heavy rain looks very likely with this system, especially during the worst time of the storm, which looks to be during the day on Friday. The strong winds could also lead to downed trees and power lines with power outages a possibility, especially on Friday afternoon and Friday night. Once that storm system pulls into Quebec province by Friday evening, it’ll pull in some very cold air for Friday night. This looks to lead to a rapid drop in temperatures Friday evening leading to the potential for a “flash freeze” of everything. This means that any water leftover from the rain will freeze up rapidly leading to very icy conditions Friday night. Here Are The Specific Details: Rain overspreads the entire area during Thursday evening with the rain gradually increasing in intensity by morning. Temperatures Thursday night will rise from the mid 30s in the evening into the 40s late at night. Winds will be East to Southeast at 10 to 20 mph with gusts to 30 mph. On Friday, expect rain all day long and it’ll be heavy at times. Be aware that street, highway and poor drainage flooding is very likely. In addition, there’s also the chance for a thunderstorm or two during the afternoon and evening, especially given the very strong dynamics of this storm. It’ll also be very windy on Friday with Southeast winds of 15 to 25 mph with gusts to 40-45 mph. High temperatures will be between 50 and 55 Degrees. Rain, which will be heavy at times, looks to continue through Friday evening before it ends around midnight or so. It’s possible that the precipitation could end as a brief period of snow and this is something that’ll need to be watched. Once the rain ends, expect a very rapid fall in temperatures just after midnight Friday night with the potential for a “flash freeze” of everything. It’ll also continue to be very windy on Friday night with South to Southeast winds of 20 to 30 mph with gusts to 50 mph in the evening and West to Southwest winds of 20 to 30 mph with gusts to 50 mph after midnight. Temperatures on Friday night will start out in the 50s during the evening, but looks to rapidly drop to near 25 Degrees within about a 2 hour time period just after midnight Friday night. By sunrise Saturday morning, temperatures across the area will be between 20 and 25 Degrees. Total rainfall amounts from the Thursday night to Friday evening storm is expected to be in the 1 to 2 inch range. Christmas Eve & Christmas Day: Even though it’s not going to look like a Christmas postcard, it sure is going to feel very much like Christmas this weekend. Christmas Eve is expected to be partly sunny, windy and cold with high temperatures struggling to make it to 30 Degrees. Christmas Day looks sunny to partly sunny, windy and cold with high temperatures between 25 and 30 Degrees. Thank You: As always, I thank you for your continued support.
