So many temp forecasts are going to bust. Yesterday NBC4 and News Channel 8 were giddy about spiking into the low 50s today. For that to verify we're going to have to get to full sun soon.
How much do you have on the ground? North of I-70 I'd agree with you that you peak in the low to maybe mid 40s. DCA might somehow magically torch..lol.
Looks to be. HM posted on twitter how some NVA on the northern edge of the MO/MS moisture plume was robbing a lot of the precip in N. MD...maybe we pick stuff back up later? This lull is sort of a let down.
Per the SPC meso analysis, the -4° degree line at 925 mbruns from roughly I-66 in VA to US 50 in Maryland. The -3° line at 850 mb runs roughly along the same line.
Pre-treatment is only to prevent the snow from bonding with the road, which aides melt off post event. It's not to keep the roads clear during the storm.
