Jan 20: Final Call Map for Wednesday Snow

Here’s my final call for tomorrow’s snow..

My rationale after reviewing the latest guidance is mostly based on a connection between the northern low and the coastal low (both weak). The darker blue area should see the most precipitation from the northern low as it dives in from the W/NW. Everywhere else is likely subject to a coating to a couple of inches. The purple area will only verify, and I repeat ONLY verify, if the coastal energy connection enhances the precipitation shield later tomorrow evening. This joined energy is modeled to become pretty robust as it moves away to the NE. If that happens a little bit earlier then the purple area verifies. Otherwise, just treat it like the widespread C-2″ light blue region.

It should also be mentioned that the purple area has the best chance to see a short period of rain during the onset of precipitation. We’ll have to monitor surface and lower atmosphere temps tomorrow before the system moves in. Ironically, this area has the potential for the highest accumulations after the changeover. We might re-visit that idea this weekend which I’ll talk more about later.

In English: Expect a general widespread coating to a few inches for the entire state. Should the storm intensify before pulling away, then SNJ/SENJ could see slightly higher accumulations. Snow should be knocking on our NW door as we approach noon tomorrow. By the time PM rush hour rolls around it could be getting pretty slick. Snow should then fall through late afternoon/early evening and clear out between late tomorrow evening and early Thursday AM. We’ll iron out any final adjustments during now-casting. Be safe! JC
