And what a snowstorm it could be . . .

The 00Z 01 March numerical guidance has converged on a solution that looks pretty promising for snow here in Annapolis. Originally both the NAM and GFS spread coastal cyclogenesis over a broad region, sometimes with two low centers separated by about 5 degrees latitude, and as a result both low models' lows moved several hundred miles offshore and generated heavy precip over the ocean. The past 18 hours have seen first the GFS & NOGAPS, and now the NAM-WRF, consolidate cyclogenesis into one low pressure center and move it NE basically along the coast. This results in somewhere between 0.5" and 0.75" QPF for Annapolis and vicinity starting tomorrow (Sunday) afternoon and ending around 18Z Monday 02 March.

The QPF, H500, and MSLP forecasts are posted below. I have my camera battery charged, and we'll see what happens.
