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 Northern Indiana wrote its last area forecast discussion before this winter weather advisory went out at Jan 24, 12:01 PM EST, 3 hours 48 minutes earlier.
Area forecast discussion, Jan 24, 12:01 PM EST, 3 hours 48 minutes before
Area Forecast Discussion National Weather Service Northern Indiana 1201 PM EST Sun Jan 24 2021 .SYNOPSIS... Issued at 432 AM EST Sun Jan 24 2021 A light wintry mix of snow and drizzle or freezing drizzle is possible today. Little to no accumulation is expected. Otherwise, skies will be mostly cloudy with high temperatures around 32 degrees. Mostly dry conditions are expected tonight before a more impactful storm system moves into the region Monday into Tuesday. Snow and ice accumulation is expected. && .UPDATE... Issued at 1013 AM EST Sun Jan 24 2021 Pockets of flurries and light snow continue to track across eastern and northern portions of the forecast area in association with brief shot of stronger isentropic lift. Patchy freezing drizzle has been reported upstream across northeast/central Illinois this morning as mid level drying has occurred in wake of this advective forcing. Better chances of drizzle are currently working into northwest Indiana and should spread west to east through early afternoon. With temperatures rising to around 30 by midday and light nature to this drizzle, currently expecting little to no impacts. Previous forecast appears to be on track and no notable changes made to period 1 forecast. && .SHORT TERM...(Today and Tonight) Issued at 432 AM EST Sun Jan 24 2021 Challenging forecast for today, with the primary question being whether or not we get any precipitation, and if we do-what form will it be in? High pressure and the dry air currently in place over the forecast area may struggle to budge eastward in any quick fashion through the period. Meanwhile, an occluding surface low entering NW Ontario this morning will sink southeastward into Lake Superior by this afternoon, and then reach southern Ontario/western Quebec by early Monday morning. This will bring a weak cold front/surface trough through our area. Ahead of the front we have some warm air advection and low level moisture to work with, but as mentioned previously there appears to be some mid level drying that works its way in from the plains. This may serve to cut out moisture from the DGZ and thus lead to more of a drizzle/freezing drizzle scenario than snow. Short term/high res models appear to be catching onto this theme, with a consolidated look to reflectivity to our west (as was seen on observations as of this writing-in the form of snow) and then a splitting to the precipitation once that forcing/better low level moisture arrives here. One area of precipitation is with the better forcing to the north of our CWA, and then another is to the south where there is deeper moisture available. Have maintained the low chance pops for today, focusing the higher chances to the northern/southern borders. Little to no accumulation is expected. At the very least it will be mostly cloudy, with highs hovering around freezing, warmest south of US 30. && .LONG TERM...(Monday through Saturday) Issued at 432 AM EST Sun Jan 24 2021 The main long term event of course is our potential winter storm Monday into Tuesday, which is leaning even closer to the ECMWF solution as of the latest model runs, and shifting the potential for more of a mix further northward. Still not high enough confidence for a watch, and per collaboration with neighbors opted to hold off for now. Have lowered QPF and overall snow totals given the dampening wave and concerns with loss of ice in the cloud as we've been mentioning in previous discussions. Have inched the wintry mix/all snow line slightly further north from the previous forecast, with snow predominantly north of US Highway 6, and a greater potential for mix the further south through the CWA you go. Expect we'll start as snow/sleet in the south monday morning, then see the transition to a mix with freezing rain/rain shift northward through Monday afternoon and evening as temperatures warm and we lose the deeper saturation in the dry slot. As we go into Tuesday morning/afternoon we'll see a changeover back to snow for all locations north of US 24. Overall, from Monday morning into Tuesday evening (7 pm) I have 3 to 5 inches north of US Highway 6, and 1 to 3 inches south (with totals decreasing further south). Still have up to around 0.1 inch of ice south of US 24, but confidence in how that will impact things given warmer temperatures at the surface is low, especially with snow/rain mixing in. The afternoon/evening commute Monday and possibly both commutes Tuesday could will be hazardous due to snow/ice accumulation and lowered visibility. In regards to Wednesday into Thursday morning weather, it's really low confidence. Models continue to disagree with one another on the upper level pattern and subsequent surface features, in addition to fluctuating back and forth from run to run on what might happen. However, at the moment it looks like we'll see dry conditions Tuesday night into early Wednesday morning beneath a weak ridge before another upper level trough/closed low encompasses the Great Lakes and Ohio Valley. While the exact timing of the low is disjointed between models, it appears we'll see some form of synoptic snow between late Wednesday morning and early Thursday morning. The ECMWF has two bullseyes of precipitation, one across our north/northwest CWA and one further south of us that just grazes our CWA borders, whereas the GFS has the low closing off further south over KY and largely impacting the southern/southeastern portions of our CWA. Have maintained low chance pops for this period as a result of the lower confidence, and it still looks to be in the form of all snow. One thing that the models do agree on at the moment is that behind the trough/closed low 850mb temps drop to around -10C Wednesday evening into Thursday, so we could see a little bit of lake effect. Where exactly will depend on the wind direction, with the GFS suggesting more of a northeasterly wind (thus keeping things over the Chicago CWA) and the ECMWF suggests more of a north- northwesterly fetch, which puts it over our northwest wind favored regions near Lake MI. It doesn't appear to be substantial in regards to accumulations at this time. Highs will be in the upper 20s and low 30s both days, with lows in the teens and low 20s. Thursday afternoon into Saturday morning will be dry as surface high pressure builds in beneath a monster upper level ridge. Any lingering lake effect from Wednesday night will diminish early Thursday thanks to the incoming subsidence. Highs Friday will be around 30F. Confidence is higher for this forecast period as models have been persistent from run to run and with one another for the past few days. Finally, We'll see a broad area of low pressure over the Central/Northern plains Saturday morning shift into the Great Lakes for the weekend, reaching the lower Lakes late Sunday night. There appear to be two upper level waves, one shifting through the Canadian Prairie and MN/WI/Upper MI, and the southern stream lifting from the central plains into Ohio. Where the two streams phase is where we see differing solutions amongst models. Have maintained the consensus pops for now given the significant differences, but it should be warmer, with highs in the mid-upper 30s and low 40s. && .AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon) Issued at 1200 PM EST Sun Jan 24 2021 Pockets of drizzle and light snow will remain possible at mainly KFWA this afternoon as a weak trough moves through. Point chances remain too low for a mention in the TAF, but did include a VIS restriction given upstream observations. A trend toward MVFR stratus and light/variable winds are expected otherwise behind this trough later this afternoon into tonight. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE.
