Summary/Conclusion

• A band of light to moderate snow moved east across the area early on the 18th.

• A band of light to moderate snow moved east across the area early on the 18th.

• The band moved quickly across the western counties, then slowed and stalled across the east.

• Snowfall totals ranged from 2 inches or less across the west, up to 14 inches across the east.

• The band lined up with a region of mid-level frontogenesis.

• Instability with this system was modest (lapse rates between 6 and 6.5 degrees C in the region of maximum lift, but little if any negative EPV).

• The overall environment associated with this event was not favorable for intense banding, however localized heavy snow accumulations did occur, primarily due to weak banding along with a very favorable temperature profile for high snow to liquid ratios.

• Tools such as the historical analogs and SREF probability diagnostics are of limited use for such localized events.
