Low End Amount - 9 in 10 Chance (90%) of Higher Snowfall

 

This map depicts a reasonable lower-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals. This lower amount is an unlikely scenario with a 9 in 10, or 90% chance that more snow will fall, and only a 1 in 10, or 10% chance that less snow will fall. This number can help serve as a lower-end scenario for planning purposes.

Expected Snowfall - Official NWS Forecast

 

This map is the official NWS snowfall forecast in inches during the time period shown on the graphic. This snowfall amount is determined by NWS forecasters to be the most likely outcome based on evaluation of data from computer models, satellite, radar, and other observations.

High End Amount - Only a 1 in 10 Chance (10%) of Higher Snowfall

 

This map depicts a reasonable upper-end snowfall amount for the time period shown on the graphic, based on many computer model simulations of possible snowfall totals. This higher amount is an unlikely scenario, with only a 1 in 10, or 10% chance that more snow will fall, and a 9 in 10, or 90% chance that less snow will fall. This number can help serve as an upper-end scenario for planning purposes.

 
The purpose of these experimental probabilistic snowfall products is to provide customers and partners a range of snowfall possibilities, in complement to existing NWS deterministic snowfall graphics, to better communicate forecast uncertainties during winter weather events.

Percent Chance That Snow Amounts Will Be Greater Than

 

This series of maps shows the probability (that is, the likelihood) that snowfall will equal or exceed specific amounts during the time period shown on the graphic. These forecasts are based on many computer model simulations of possible snowfall totals.

Snowfall Totals by Location

 

These tables show the snowfall forecast for individual locations. The tables provide the same information as the maps on this web page, just shown in a different way. The "Exceedance" option shows the chance that snow will exceed a certain threshold. The "Range" option shows the likelihood of snowfall being within a certain range. All of these values are valid for the same time period as depicted on the graphics.

Low Tracks Graphic

The graphic depicts the forecast location of significant surface lows impacting the 48 contiguous United States in 12 hour increments out to 72 hours into the future.

The low position and track forecast by NCEP WPC meteorologist is in white. Each low position is accompanied by a lead time (Eastern Time). The circles around each low represents a 75% probability the observed low will be located with the circle. Note: The probability is derived using previous season's verification data. For reference, existing surface lows are depicted with a red marker without yellow circles.

Precipitation Onset

Most likely time of winter precipitation onset (snow, sleet, freezing rain). Rain is not included here. This information is provided when we issue a Warning or Advisory for expected snow or ice accumulation; typically six to 24 hours in advance. Times are only given for places that are under a Warning or Advisory. They will be blank in areas outside Warnings or Advisories.

Reported

As snow and/or ice reports come into the NWS (you can email reports to us here. or Tweet to @NWSCLE), we will pass them on here. With the map linked here, and the supporting reports in the Public Information Statement, you can keep tabs on how much has fallen.

Area Forecast Discussion
National Weather Service Cleveland OH
351 AM EDT Wed Apr 25 2018

.SYNOPSIS...
Low pressure over North Carolina will track northeast along the
Atlantic coast today drawing a cold front east across the local
area. High pressure will build across the region tonight
and Thursday ahead of a cold front that will move east across
the region on Friday. A second cold front will quickly follow
Friday night as another low drops across the Great Lakes.

&&

.NEAR TERM /TODAY THROUGH THURSDAY/...
Low pressure over North Carolina will track northeast to New
Jersey by evening. Moisture over the region early today will get
pulled east with the low through the day as high pressure
builds in from the west. Low level moisture however will be slow
to exit. Will keep clouds in the east through the day and break
up clouds west during the afternoon. Will begin with likely to
categorical pops east and chance pops elsewhere for light rain.
For the afternoon will drop the east to a chance and remove pops
west. Overnight, both the NAM and GFS hold onto low level
moisture northeast while drying out the rest of the area. Based
on this will hold onto clouds east/northeast much of the night
with clearing continuing elsewhere. For Thursday again both
models actually expand 850mb rh 80% or better across the area
although given high pressure will be over the area will side
with the optimists and go with PC.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SUNDAY/...
A southern
stream system that largely bypasses the Ohio Valley Thursday
will shift across the Appalachians and move to the mid- Atlantic
coast Friday. That will leave high pressure weakly in place
across the local area Thursday night. A weak cold front, lacking
in moisture and much lift, will cross the area on Friday. This
may bring an isolated or scattered shower with it. It has been
consistently advertised as having limited impact. A stronger
shortwave digs into the base of the trough across the Great
Lakes later Friday. This has a little more potency and may bring
a shower to northern OH/nw PA Friday night into Saturday
morning. Then Sunday we begin the transition to ridging aloft
with high pressure at the surface. Temperatures will be near
normal Thursday night/Friday, slide back some for Saturday and
then begin to warm for Sunday. Sub- freezing lows are possible
Saturday night across northeast OH/nw PA especially if we get as
much clearing as we are expecting.

&&

.LONG TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/...
Early next week is looking to be terrific. High pressure sets up
across the southeast U.S./Bermuda by Tuesday. The ridge aloft builds
into Tuesday and southerly flow will bring much warmer temperatures
to the region. Precip will stay out of the forecast.

&&

.AVIATION /06Z Wednesday THROUGH Sunday/...
Low pressure over North carolina will turn northeast and move up
the east coast today. Moisture associated with the system has
spread light rain with MVFR and IFR restrictions across the
area. Most IFR was across western OH, west of an inverted
surface trough. Am expecting the IFR to spread east late tonight
and Wednesday morning as the trough pulls east out of the area.
Expecting a mix of MVFR and IFR Wednesday morning with
conditions lifting to MVFR most places late morning into
afternoon. Expect improvement to VFR from the west mid/late
afternoon.


OUTLOOK...Non-VFR Wednesday evening into early Thursday mainly
east.

&&

.MARINE...
Areas of fog will remain on the lake until the cold front across
southeast MI crosses today. That cold frontal passage will shift
winds around to the north-northwest and increase them to 15 to 20
knots for a short time this afternoon/evening. This will be enough
for a short small craft advisory across the central third of the
nearshore waters this evening. After this brief uptick in winds
conditions settle with high pressure shifting over the lake for
Thursday/Thursday night. A weak cold front crosses the lake Friday
followed by another late Friday night/early Saturday morning. This
will make for a little chop across the east half of the lake on
Saturday. High pressure builds across the Ohio Valley and lower
lakes for Sunday.

&&

.CLE WATCHES/WARNINGS/ADVISORIES...
OH...None.
PA...None.
MARINE...Small Craft Advisory from 6 PM this evening to 4 AM EDT
Thursday for LEZ146>148.
