Snow Showers Return For Tomorrow, True Arctic Air By Mid Next Week

JAMESTOWN – While most of the lake effect snow has tapered off some pockets of light lake snow is still possible through the afternoon. A clipper system moving through will spawn another chance for widespread show on Friday before a very brief warmup will occur over the weekend.

Any pockets of lake effect will come to an end through the day with most spots only picking up around an inch or so of additional accumulation. It will still remained breezy with health west wind 10 to 25 MPH with gusts nearing 35 MPH at times. Those gusts could be just strong enough to blow around some of the loose snow and reduce visibility at times. Highs 28 to 36.

Tonight will start dry with mostly cloudy skies however as the clipper system moves closer towards the region, snow will return from west to east by dawn. Morning lows 24 to 31 with west wind around 10 MPH.

The morning commute on Friday is likely going to be slow with area-wide light to moderate snow from that fast-moving clipper system. The system could lay down another one to three inches by Friday evening. Highs 30 to 35.

Tomorrow night is the annual Jamestown Christmas Parade in Downtown Jamestown. While snow showers could still be falling through the parade, they will taper off later in the evening. Temperatures will not be moving much; hovering near 30 degrees.

Most areas on Saturday will stay in the upper 20’s with a cold northernly wind flow. There will be some here and there breaks int he cloud cover but we’ll call the majority  of the day mostly cloudy.

As we’ve been talking about over the few days, a warmup will come our way over the second half of the weekend. Temperatures will rise into the lower to upper 40’s both Sunday and Monday with rain showers early next week.

However things will go downhill on Tuesday. As we often mention, the warmest temperatures are always out ahead of a Cold front. The official highs on Tuesday will likely occur in the morning. As the front sweeps through, temperatures will fall along with it, likely ending the day in the upper 20’s. It will also become very windy as well. While it’s still a little too early to give a range, model data does suggest gusts that could warrant advisories.

Behind that Cold front, strong Arctic air will fill into the region for Wednesday. Highs will barely struggle to hang into the lower 20’s with a strong wind. There are also indications of heavy lake effect snow setting up Tuesday night through Wednesday as that Arctic air moves across the warmer lake waters.

Keep in mind, we are still six to seven days out so it is scientifically impossible to go into full details on any lake effect. We will have much more information as we get closer.
