Will The Vermont Rains Coming This Week Be Just What The Doctor Ordered Or Too Much Of A Good Thing?

Summer flowers this morning in St. Albans, Vermont.
The gardens are a bit parched and need rain. We'll
get some, but will it ultimately be too much?

Vermont is in for one more gorgeous summer day today. As previously advertised, this is one of the best weather weekends of the year. 

Today will be almost the same as yesterday, with highs in the 80s under generally sunny skies. There's a bit more wildfire smoke in the air than on Saturday ,but it shouldn't be thick enough to be hard on our lungs or dim the sun much. 

It looks like rain chances will slowly increase between tomorrow and Tuesday. But the showers and thunderstorms will be slow to work into Vermont. And there are big questions as to whether we will have a lot of rain or practically nothing. 

Even though the bulk of the rain will come between Tuesday and Thursday, we still don't know the outcome. We will have one of these three options: 

1. At least parts of the state get cheated, and needed rain doesn't materialize to any great extent So far,  this looks like the least likely scenario

2..Repeated showers and thunderstorms, and possibly a period or two of just steady rain comes through over the course of three days. But the downpours are not too excessive. So we get a nice soaker, but no threat of flooding. This is exactly what we want, and the forecast is leaning slightly toward this scenario. 

3. Too much of a good thing. The downpours linger and become frequent and heavy. There's so much rain that we end up with flooding problems. At this point, if this scenario does happen, it looks like southern Vermont has the highest rise. 

Here's how forecasts think things will happen, including the questions. 

MONDAY

Some scattered showers and thunderstorms might develop during the afternoon.  They're most likely to focus on the Adirondacks. Over here in Vermont, most of us won't see any rain. Perhaps 20 to 30 percent of us will see some at least some rain. It will stay very warm, with highs probably well into the 80s. It'll be slightly more humid than today, but not insanely oppressive.

TUESDAY

Here's where the question marks in the forecast really start. Tuesday through Thursday, it will depend on whether an upper level area of low pressure forms and nearly stalls. And exactly where it happens. 

For Tuesday, it looks like it will be more humid, with a greater chance of showers and storms than on Monday. If the weather system comes in as just a disturbance, we'll have a fair number of afternoon and evening showers and thunderstorms, but nothing incredible.

 If a an upper level low pressure system forms, the rain will be more widespread and the downpours heavier.  That could lead to isolated instances of relatively minor flash flooding. 

For now, Vermont, and most of New England for that matter, is under a marginal, level one out of four level risk of isolated flash floods. 

WEDNESDAY

This is the big question mark day. It'll pretty much definitely rain, at least somewhere in Vermont. The question is, will that upper level storm form, and if so, where will it meander?

If the upper level low does form and stall, somebody under or near it or could receive some flooding rain. Some weather models don't predict this storm to form. Others say it will, but it will happen south and east of Vermont, so no real trouble for us. A few other models have this thing over or near Vermont, opening the door for potentially torrential rains. 

I'm not sure which scenario will unfold. In fact, nobody is sure. So we'll have to wait and see.

For now, southern and central New England, including southern Vermont, is under a slight risk, level two out of four level risk of flash flooding. It's unusual to have that level risk three days in advance, so we'll have to watch this. 

I'm not raising flood alarms yet, but we'll have to watch this.

THURSDAY

Still some lingering showers, but whatever weather system will be harassing us will be starting to move out.  

As always, we'll see how this develops.  It is one of those situations in which we won't know how this will play out until we get much closer to the event.
