Cold front on the way - precipitation will follow close behind...

...For the period now until 6am Tuesday...
Rain showers will develop and/or increase across the local area from now through 11pm and then continue through about 3-4am.

Winds will shift to the North and increase to 25 mph sustained with frequent gusts of 30-40 mph between 9pm and 11pm this evening as a strong cold front moves from North to South across the area.  Temperatures will fall to around freezing across most of the area by around 4am, and precipitation will begin to mix with freezing rain, sleet and/or snow at that time.

Light ice accumulation may begin as early as 4-5am, and is likely to continue to increase through dawn.  Icy spots are likely to develop on elevated surfaces first (i.e., bridges, overpasses, etc.), and then begin to develop on other surfaces especially toward dawn.

...Looking ahead to after 6am Tuesday...

Periods of freezing drizzle, freezing rain, sleet and/or light snow will continue through 9-10am, and then change mostly to sleet and/or snow from 9-10am through 12 Noon.  Additional ice and/or sleet/snow accumulation is expected during the morning hours.  Please refer to the last full blog post for additional details on the Tuesday daytime hours.
