Attached are two 24 hour EPS graphics from the 12z/10 cycle that are significant for D6-7. The CMCE and GEFS are much less of snow risk for the northeast USA, so far. This thread is started because of the several consecutive cycles, although variable placement, EPS persistent snow threat for the I84 or I95 corridor, and it's possible snowfall outcome for NYC. Also is attached the 19z/10n Blend of Models from the NWS as a sketchy idea for I95. Reminders: The CMCE and GEFS are weak with the snow risk. Tags may be adjusted in a few days as it becomes clear whether our NYC subforum only gets a short period of snow/flurries in the wake of a strong windy cold frontal passage with single number-teens wind chill by Wednesday morning, or we realize a nice coastal wave of low pressure that produces hazardous wintry weather for the majority of the NYC subforum, then followed by a shot of the wind driven cold. This system is not as clear cut at D6-7 as previous storm threads in Dec-Jan, so uncertainty exists. [Typo on headline Thread. updated 854PM/10] -
This is was recorded using an electronic barograph. This is about a 24 hrs period. I've been seeing spikes like the one the occurs at about x axis = 80,000 from time to time. Not 100% it's a real pressure change but I don't know what else it could be. The sensor is a BMP280, recorded about once a second. It's just outside my window, I don't think it's wind gusts. Anyone else commonly seeing this on their barographs?
