    WXD Alert: Post Discussion
    Convective development begins in the evening hours of Friday as the first thunderstorms of the year for most of the region. At the moment, the areas most likely to see a thunderstorm are along the I-95 corridor through North Carolina, Virginia, Maryland, Delaware, and New Jersey. The northward extent of the convective development has been tricky to forecast, but the latest HRRR, the 12z NAM, and the 12z HRDPS have suggested that the NYC metro area, Long Island, and the Connecticut coastline will be enveloped by heavy rain

    ...Widely scattered strong to severe thunderstorms may occur from parts of central/east Texas to the lower/mid Mississippi Valley on Wednesday. At the surface, a deep surface low will develop east/northeast from eastern CO to eastern NE during the period. A cold front will trek east/southeast across the central and southern Plains during the afternoon into overnight hours. Ahead of this feature, convection will likely be ongoing along a dryline/pacific cold front from south-central OK into central TX. Given these combination of factors, the possibility exists for a few mini supercells. The tornado risk will be conditional on the degree of destabilization. Strong wind profiles with effective shear (60+ kt), will conditionally support a damaging wind threat with the more organized segments of the larger-scale convective band expected to move east from OK/TX towards the MS Valley.The strong to severe threat will likely cease coincident with the nocturnal cooling during the evening.

    ...Heavy snow for the Sierra... ...Heavy rain possible for Coastal California will lead to excessive rainfall over parts of Southern California.. A deep upper-level low over the Pacific will move onshore over California on Wednesday then moves farther inland to the Northern/Central Plains by Thursday. Moisture associated with the system will stream into California and begin to wane overnight Wednesday. The moisture and energy will aid in producing rain, heavy at times, over parts of California and snow, heavy at times, over the higher elevations of California through Thursdays morning while beginning to wane.

    This is a quick storm, with precipitation occurring in a 12 hour timeframe, but it could have significant impacts on Monday. Once again, the uncertainty in track and location of any banding activity is leading to an unusually "unstable" forecast with "nowcasting" changes almost certain. Winds do not appear to be significant at the moment, with the wind threat being maximized the further east a location is. Behind the system, a Canadian high pressure system brings an Arctic airmass to settle in through the middle of the week, so any snow on the ground will be sticking around for quite a while.
