Exton averages about 32" a season so maybe a big MECS will be needed!

Snow picking up in intensity here in NW Chesco Temp 31.7

Only in an advisory here in NW Chesco but my point and click a bit more aggressive (4" to 8" of snow possible??) - likely the usual problem of unable to break out NW Chesco from SW Chesco... Snow before 3am, then snow and sleet. Low around 27. East wind 5 to 9 mph. Chance of precipitation is 100%. New snow and sleet accumulation of 1 to 3 inches possible. Tuesday Snow, freezing rain, and sleet before 9am, then freezing rain and sleet between 9am and 3pm, then rain and sleet after 3pm. High near 36. East wind 10 to 14 mph. Chance of precipitation is 100%. New ice accumulation of less than a 0.1 of an inch possible. New snow and sleet accumulation of 3 to 5 inches possible.

Just starting to snow lightly again here in NW Chesco for the 1st time since early this AM. Temp at 32.9 DP 28.0

Latest WXSIM with 12z data has no snow just some light sleet starting this PM and continuing all night with around 1" of sleet accumulation by 7am tomorrow morning. Sleet becomes moderate by 830am tomorrow morning with another 1" to 2" of IP accumulating before a change to ZR by 1130am Then ZR thru 3pm before temps rise above freezing by 330pm. Then another 1.18" of rain before it ends by 330am on Wednesday. Total precip 2.81" with 1.44" falling as some form of frozen.

Yep - no idea - let's see what it does with 12z data in about 15 minutes or so

WXSIM with 6z data with 1.3" already on the ground - nice forecast so far. WXSIM shows light now and IP continuing most of the day with another 1" or so accumulating by 10pm tonight. Snow should become all sleet/IP by midnight and become moderate by 3am tomorrow morning. Sleet moderate at times will continue to fall till around 10am with 2" to 3" more inches of snow/sleet falling before transitioning to rain by 1pm tomorrow afternoon. Total snow accumulation 4" to 7" . Wxsim still shows another 3.15" of rain falling tomorrow PM into Wed AM before ending

East Nantmeal Twp Chester County Pa 1.3" as of 730am Snowing steadily in NW Chesco Temp 27.5

Light Snow underway here in NW Chester County Pa - temp 30.5 DP 19.4

As we have talked about quite a bit here lately - remember snow and sleet are considered the same thing for reporting purposes - because both can be shoveled - if you have 2" of sleet and 1" of snow that is actually 3" of snow

Latest WXSIM with 12z GFS/NAM blend Light snow starts around 830pm tonight. Moderate snow by 1130pm back to light snow by 2am tapering to flurries by 6am with 1" to 2" of snow by 7am. Flurries continue during the morning with steady snow redeveloping by 1130am and continuing till 4pm. Then Sleet/IP from 4pm- thru 7am Tuesday morning then a mix of IP/ZR till 11am (total Snow/sleet of 4" to 6" with most of that IP) then very heavy rain all PM with another 4" of rain falling (that looks wrong!) So basically 2.04 inches of qpf falling with temps below freezing and then 4.08" with temps above freezing

Thanks for the clarification Ray!! Good to see you on this forum!! take care

WXSIM update with 6z GFS and 12z NAM for NW Chester County Pa Snow arriving tonight by 830pm becoming moderate by midnight. Back to light snow by 3am and ending by 7am with 1" to 2" of snow. Snow begins again by 230pm quickly changing to Sleet/IP by 5pm light IP much of the night becoming moderate sleet by midnight with Heavy IP developing by 3am and continuing through 9am Tuesday. By 930am 3" to 5" of sleet would have accumulated. Sleet mixes with and changes to ZR by 10am and becoming all rain by noon. Heavy rain during the PM with up to 2.5" of rain with temps rising to the mid-30's

Hey Steve, according to NWS guidelines you never use a ratio for measurement that is always going to be wrong. IP/Sleet accumulation is exactly the same as snow. If snow changes to IP....wipe the board and start over with new measurement in inches of sleet accumulation. Bottom line is snow and sleet are exactly the same and recorded as snowfall. If you get 4 inches of snow and then 2 inches of sleet you record that as 6 inches of snow

Wxsim with 12z data obviously trended colder and icier based on the latest models. It now has snow arriving by 830pm tomorrow night with moderate snow at midnight with 1" of snow by 1am Monday. Light snow and flurries continue till 6am with 1.5" of snow. Light snow and sleet arrive again by 530pm with moderate IP by midnight - IP over to ZR by 930am with a total of 3" of IP and then another 0.60" of ZR before rising above freezing by noon - Heavy rain all PM with 2.50" of rain before ending late at night with temps rising to 37 degrees

I can't tell it just says NAM.....

High today in East Nantmeal was 62.4 - our warmest day since the 68.9 back on November 2nd. Nowhere near the record for today of 66.0 set back in 1991. Of interest down the shore in Sea Isle City we were able to overcome the sea breeze unlike yesterday where the chilly 36 degree ocean won out and kept temps in the 40's. Today we reached 61.6 at the beach. Hope all enjoyed the last couple days....reality returns and liking some snow prospect for the next Mon-Wed time frame

1.3" total snow in East Nantmeal Twp. Chester County PA with 5.3" of snow in the last 4 days. Seasonal Snow is now up to 16.0" only 1.6" below normal for the season to date.

Steady snow continues as it has all day temp has dropped to 16.7 down from high of 17.6 continues to accumulate slowly certainly over an inch (over performer) here will measure shortly when snow ends as back end is approaching

Continues to snow at a steady pace here in NW Chesco in East Nantmeal Townshhip with just slightly under an 1" of snow call it 0.9" so far - already more than expected - no doubt excellent ratios Temp up to 17.5
