What forecasters said that day
The local office's own words before this winter weather advisory went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Charleston, WV wrote its last area forecast discussion before this winter weather advisory went out at Jan 18, 1:14 PM EST, 2 hours 3 minutes earlier.
Area forecast discussion, Jan 18, 1:14 PM EST, 2 hours 3 minutes before
AREA FORECAST DISCUSSION National Weather Service Charleston WV 114 PM EST Mon Jan 18 2021 .SYNOPSIS... Upper trough exits the area today with lingering light snow showers expected. Weak cold front Tuesday. High pressure end of the week. && .NEAR TERM /THROUGH TONIGHT/... As of 850 AM Monday... Made some slight changes to chances of precipitation this morning to better represent current radar trends. Mostly just expanded slight chances to the west and south a bit as some light snow showers are continuing to occur. The larger band of snow, currently along southeast WV, has almost moved out of the region. Some flurries and light snow showers will to be possible for the first portion of the day, mostly along the western half of the area, and will likely continue to linger along the mountains for much of the day. As of 242 AM Monday... An upper level trough exits this morning leaving a flat wave of vorticity across the area through tonight. However, model soundings show we are losing moisture within the dendrite growth zone. This will reduce the coverage and intensity of snow showers expected from time to time today. The sun may try to filter between clouds breaks this afternoon. Sub freezing temperatures this morning will increase few degrees above freezing this afternoon, to dip back down this evening and tonight. Max temperatures this afternoon will reach the mid 30s lowlands, ranging into the upper teens highest elevations of our northeast mountains. Winds will remains west southwest with few gusts possible. && .SHORT TERM /TUESDAY THROUGH WEDNESDAY NIGHT/... As of 346 AM Monday... A weak surface low across the Great Lakes will push a cold front southeastward across the area on Tuesday with scattered snow showers Tuesday morning transitioning to rain showers across the lowlands during the afternoon hours. However, precipitation activity should remain as snow throughout the day in the mountains. By Tuesday evening, a shortwave will approach the area from the northwest and bring a reinforcing shot of colder air into the area as models suggest that 850mb temperatures will dip down to about the -10C to -12C range. The cold air advection combined with saturation intersecting the DGZ and WNW flow should lead to an increase in upslope snow potential in the mountains Tuesday night into Wednesday. Thus, will include slight/chance PoPs in the mountains during this time but remainder of the area should be mainly dry with just a small chance of occasional light snow shower or flurries as forecast soundings do suggest that plenty of low level moisture will be in place. Current thinking is that about 1-3 inches of snow for the mountains in the Tuesday night through Wednesday afternoon time frame is reasonable at this point, but this may have to be increased a bit more in subsequent forecast shifts depending on how long saturation in the DGZ layer can hang on. Otherwise, expecting a decreasing trend in snow shower activity by the late afternoon and evening hours on Wednesday as high pressure builds into the region. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 346 AM Monday... Our warmest day of the week should occur on Thursday as low level flow becomes more southerly as our area will be positioned along the northern periphery of a surface high centered across the southeast US. This should allow highs to reach about 5 degrees above normal for Thursday afternoon. In addition, a weak wave aloft may allow for some development of rain/snow showers during the day, but recent guidance and most GEFS ensemble members have been trending drier so overall chances for precipitation on this day should be pretty low for the most part given limited forcing and moisture. By Friday, a southern stream system is expected to be quickly pushing eastward across the Deep South but precipitation shield associated with this system should remain south of our area. Otherwise, high pressure in the Great Lakes should keep conditions mainly dry across our area for most of the upcoming weekend, but precipitation chances will start to increase by the late Sunday into early next as the next system approaches the area. In addition, temperatures are generally expected to be below normal through the upcoming weekend. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... As of 1240 PM Monday... The upper level trough continues to move away from the area as light snow showers continue, mostly along the mountains. BKW/EKN should be the main sites to be affected by these light showers or flurries over the next few hours, but should see a break in precipitation by later this afternoon into this evening. MVFR/IFR visibilities could be possible if any additional showers move over these sites. MVFR ceilings start the period for all sites and will likely persist through the night. HTS and maybe CRW may see a lift in ceilings to VFR briefly as high pressure tries to move into the area, but will fall back to MVFR late tonight. Late tonight into early tomorrow morning a disturbance will move into the area along the west, leading to chances for snow showers across much of central WV, and continuing off into the mountains. MVFR/IFR visibilities will be possible with these snow showers. Additionally a cold front will cross tomorrow, leading to brief periods of IFR ceilings possible as it moves through. Behind the front, any ceilings that dropped into the IFR range should lift back up to MVFR and any snow shower chances should taper out by the afternoon, with the exception of the most eastern/mountainous sites which may have snow showers lingering until the end of the period. Westerly/southwesterly winds start off the period at around 5-10KTs, with gusts up to around 15-20KTs possible through this afternoon. Winds will lighten up slightly tonight, becoming more southerly, and should pick back up tomorrow around 5-10KTs. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing and extent of snow may vary with the disturbance late tonight. Timing of IFR ceilings tomorrow may vary from forecast.
