02. cold Waxes and Wains with the artic highs as they move
03. warm ups are short lived in january and febuary
04. this is the dead of winter as they say
Though Meteorological WInter starts december 1st its not till december 21st or so that astronomical winter starts. june 1 is Meteorlogical summer . and such is the astronomical there are is the spring and fall equinox's that mark the begining of astronomical spring and Astronomical fall but the fall is really September 1st at least Meteorological fall
what we are getting in the mid atlantic is freezing rain and according to some models the Freezing rain will hang on longer in the higher Elivations north and west of the cities of Washington and Baltimore and they are at the greatest risk of getting a 1/10th of an inch to 1/4th of an inch though at 1:24 pm Est The NWS sterling virginia has not issued a witner advisory yet i expect they will soon around the 2 pm or so confernce call with the Weather serivce office where i work and me we will coordinate a statement and any possible advisories at that time the sounding National Weather Service offices have issued Winter Weather advisories and Freezing rain advisories as well for the area around maryland and i dont know whats keeping Sterling From issuing a advisory for the area i guess they want to wait till the afternoon confernce call or if not that then the evening confernce call. we shall see what happens. current temperature is 35.4 degrees pressure is 30.54 Falling highest pressure was 30.67 that is not a record i dont think we will have to see what the highest presssure was at National Airport and the 2 other airports before we determin if its a record or not it was certinly high enough to cause aches and pains in weather sensative people like my self.

its not going to get much warmer than that i will post a map of where i think the best possiblity for iceing is going to be tonight and tomarrow notice its above 100 Ft in elevation. This is the NAM model prediction where the The ZR or Freezing Rain will hang on longer Knowtice that the I-95 fall line is the classic boundery to the east of the northern suburbs and emediate northern and western suburbs the ice will hang on a bit longer there som maybe a tenth to a quarter of an inch.
These maps just show the potental acceation of ice and you see that its along and west of I-95 corridor between I-95 and I-270 and montgomery county is right in that zone its going to be from I-70 and I-83 and I-270 and that is the range of the ice and the estern most extent is I-95.
The map below is NAM model showing what areas are going to be affect with ZR or Freezing rain.
