7 PM Update: Most sn shwr activity has diminished in cvrg and intensity, xcpt one just south of Houlton which we issued a special statement for brief sn sql conditions. Otherwise, chgs this update include adding more topo affects on wind, cld cvr, and PoPs. Lastly, latest temps/dwpts were used in updating fcst hrly temps thru the ovrngt hrs with no chgs attm to fcst ovrngt lows. Orgnl Disc: We will remain in a strong northwesterly flow around deep low pressure situated to our northeast tonight into Friday. Snow showers across the area, mainly over central and northern locations, will taper off this evening. Tonight will then remain mostly cloudy with lows in the mid 20s across much of the area. Friday will remain mostly cloudy as the deep low to our northeast continues to slowly back away. Snow showers are likely during the midday and afternoon Friday. Cold air moving in aloft, divergence aloft, and instability created by the mid March sunshine will likely produce some convective snow showers over central and northern areas. Winds aligned through a deep layer of the atmosphere also favor the potential for convergence downstream from the Laurentians. This could enhance snow showers from central Aroostook east southeast across northern Penobscot counties into southeastern Aroostook county producing some locally heavy snow showers.
