Update on Winter Weather Advisory
We’ve been seeing a lot of photos of ice forming on anything that is NOT in direct contact with the ground, like benches, leaves, and metal railings.
Temperatures here at the surface have been hovering around 30-34° all morning, meaning that we don’t a have a major ice storm underway. We really need temperatures in the 20s for icing to occur on many roadways. That said, we could see a few bridges or overpasses have a patch of ice or two on them. So still use caution.
The WINTER WEATHER ADVISORY will expire at noon as any ice should be melted by then.
We didn’t have sleet or snow because a fairly thick area of warmer air moved in the upper atmosphere, a few thousand feet up. As snow/ice fell through this warm layer, it melted completely as it hit the ground…just as rain. The rain did then freeze on those elevated surfaces and objects, like power lines, but only a light icing thus far.
We do expect all precipitation to come to an end by lunchtime today. By afternoon, still mostly cloudy and cold but above freezing.
Overnight, as the upper level low moves overhead, we’ll have the potential for a few snow flurries. At this time, we’re not expecting a big snowfall, but it bears watching. Anytime we get this set-up, there’s a lot of cold air in the upper levels under the center of the low. If we have enough moisture, that cold air can squeeze out some snow. More moisture = more snow and vice versa. Thinking is still that a few flurries would melt quickly after sunrise Tuesday.
Things really improve after tomorrow. Sun is back by Wednesday…so no travel worries at all. Thanksgiving Day is looking milder too.
