Heavy rain Tuesday, possible snow late week

High pressure that has taken control of our weather Sunday & Monday will move off shore on Monday night allowing a low pressure, coastal storm to move in during the early morning hours on Tuesday. Expect heavy downpours at times and gusty winds.

This will impact the morning commute on Tuesday, not a day you want to leave home without the umbrella. No snow is expected from this system, we just don't have that cold air in place to allow for any frozen precipitation. The storm should wrap up by the afternoon, leaving some showers and clouds in its wake.

High pressure will build in, bringing down colder air from Canada through Thursday. Unfortunately, this is in bad timing with another coastal storm that is now forecast to form hot on the heels of the last storm. This will (currently) mean the potential for the first accumulating snowfall of the season (based on current guidance). Thankfully, forecasts show the shoreline missing out on snow, in favor of rain.


The latter part of the week is not well forecast. As of Saturday morning, no model forecasted this storm. As of Sunday, both global models - the GFS and the Euro - now forecast this storm with potentially accumulating snowfall for the state.  While there is good agreement on storm track, the timing of the storm is an issue, and the fact that this flip occurred in the models means there is little continuity of forecasts to draw confidence upon. On top of all that - the forecast is still some 5 days out, and it is quite common for forecast confidence to be significantly lower at those timeframes. Bottom line - it's something to keep an eye on.
