Monsoon's Tuesday afternoon update...
I'm sticking with all aspects of my earlier forecast except the timing of the changeover: it appears warmer air will move into the upper levels of the atmosphere earlier, causing a sooner changeover. So it is: snow until just after midnight, when it will mix with then change over to sleet and freezing rain.
Since surface temperatures will still be below freezing when we are to commute in the morning, I think things still look favorable for a delay or cancellation.
Freezing rain may change over to all rain in the later morning and afternoon before ending as snow showers in the evening.
For Wednesday... Chance of cancellation: 75% Chance of delay: 80%
