Imminent Bombogenesis

[edschweppe]

Yes, "bombogenesis" is the term the local National Weather Service office uses when describing the rapid intensification of coastal storms, especially around the "benchmark" at 40N 70W:

00z Guidance is in general agreement with the upcoming system on
Thursday. Potent shortwave moving into the Gulf of Mexico will be
the focus for our system as it is along the base of the elongated
trough. Secondary shortwave pushing through the Midwest will help
tilt the trough negative as our surface low begins to develop.
This surface low will strengthen as it moves up the East Coast
towards New England today and tonight. This negatively tilted
trough will aid in the surface low to undergoes rapid
intensification as it moves near 40N/70W benchmark.

Latest trends is to continue to push this system a bit westward as
well as stronger near the MA coast. 00z models have this system
undergoing bombogenesis with sub 960 mb low tracking southeast
of the 40N/70W benchmark and then into the Gulf of ME Thursday
afternoon/evening. In fact, some EPS members show the low
falling below 950mb. 00z Guidance is still struggling with its
Mass fields as there is a lot of convective feedback/latent heat
issues. Hopefully with the development of the cyclone down in
south Florida over the next few hours, models will begin to have
a better handle on this system. Current thinking is with the
placement of the lows and current shortwaves, the westward trend
in the system can still continue over the next 24 hours. The
06z NAM is one example and currently believe it to be an
outlier. However, it could show the trend that models will push
the system west. So we will need to continue to evaluate this
storm over the next 12-24 hours.

The good news is that I don't have to worry about a commute; the bad news is this will probably mean we cancel the first choir practice of the new year.
