Another Norlun Trough Set To Graze The Area Tonight

Hello everyone!

Special update this evening to cover another Norlun trough type setup that looks to bring another round of light snow tonight and into early tomorrow morning. While the heavy snow bands usually associated with Norlun troughs will remain mostly offshore, an axis of shifting winds with reasonably impressive instability and some lift too will make an appearance mainly east of Brunswick tonight into tomorrow morning.

A low pressure area that brought snow and ice to the southeast US will move too far offshore to bring major impacts though a Norlun trough, basically a wind shift line, will extend to the NW of the storm bringing coastal areas some snow. Snow will be concentrated between 11 tonight and 9 tomorrow morning.

While snow will mainly be light, especially west of Brunswick, some moderate to even heavy bursts of snow are likely across Midcoast areas. The map above shows intense upward motion across Midcoast areas tomorrow morning signaling bands of heavy precip are possible. The areas most at risk for heavy precip will be east of the Bath/Brunswick area.

Here is the expected snowfall from this event. Not a lot, but the driveway will once again have to be cleared especially over eastern areas.

In case you were wondering if this event was a Norlun trough, Weir Lundstedt, one of the two ‘discoverers’ of the Norlun trough (he represents the ‘lun’ part of Norlun) confirmed yesterday evening this did in fact look to be a hybrid Norlun event.

Snow Moving Out This Morning, Warmer Temps Follow For This Afternoon

Hello everyone!

Today will be an interesting one for sure as our storm pulls away. This morning expect clouds with a few lingering flurries mainly over Midcoast Maine as well as York County. Any leftover snow activity should be moving out in the next hour or two so the digging out can begin. Temps this morning are mild by comparison to previous weeks, 10’s inland and 20’s elsewhere with even a few 30’s showing up along the immediate coast!

Temps will warm even more today as a cold front comes through. Let’s just say the airmass behind the front isn’t all that cold… What the front does is basically slices and dices the cold airmass that is in place this morning so that it can move out of the way (notice the warm air that tried to work in last night was met with little success). As a result, temps will rise into the 30’s for everyone with readings near 40 along the coast!

For Portland, today will likely mark the first day since January 5th that the temperature has been at or above average.

Our mild temps today do not last as another cold front moves through this evening. Winds will pick up tonight as the cold air moves in and we go back to the bitter cold. Our next chance for snow arrives Wednesday and it looks to be in the form of snow showers or maybe even light snow.
