We are continuing to closely monitor a developing winter weather situation
for Tuesday of next week. We are becoming increasingly confident that this
situation may cause travel and other impacts for possibly significant portions
of the area during the day on Tuesday. Please see below for details:
Periods of light rain are expected to mix with and then change to a mixture of sleet, freezing rain and possibly light snow starting around 6am on Tuesday morning. Present indications suggest that this mix will then continue into the afternoon hours before decreasing in coverage and intensity between 3pm and 6pm.
Temperatures on Tuesday will range from a high of 48 during the pre-dawn hours (about 1am) to a low of 27 by 9pm on Tuesday, as temperatures are expected to fall throughout the daytime hours. Hence the forecast increase in the potential coverage (and intensity) of wintry precipitation on Tuesday vs. the last update.
Present indications suggest that ice accumulation of up to 0.1 inch is possible with this event. Ice accumulation of this amount would mainly form a light glaze on exposed surfaces, especially metallic surfaces and colder elevated surfaces such as bridges, overpasses, etc., (especially if they are untreated). Tree limbs may also start to see a glaze-over especially if the near 0.1 inch ice amounts are realized. Most of the light ice accumulation would likely occur on Tuesday morning, based on present indications.
In addition to the potential for light ice glazing, present indications suggest that sleet and/or a combined sleet/snow accumulation of up to 0.5 inch is possible with this event. This would most likely occur on Tuesday afternoon, based on present indications.
Transportation impacts appear increasingly likely across many parts of the local area beginning Tuesday morning and possibly continuing into much of the daytime hours if temperatures continue to fall and precipitation continues to be produced across the area as described above. At this time we would describe such conditions as "probable".
We will continue monitoring the situation and issue updates as conditions warrant.
