What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Indianapolis, IN wrote its last area forecast discussion before this winter storm warning went out at Dec 16, 3:06 AM EST, 49 minutes earlier.
Area forecast discussion, Dec 16, 3:06 AM EST, 49 minutes before
Area Forecast Discussion National Weather Service Indianapolis IN 306 AM EST Mon Dec 16 2019 .UPDATE... The SYNOPSIS...NEAR TERM and SHORT TERM Sections have been updated below. && .SYNOPSIS... Issued at 301 AM EST Mon Dec 16 2019 A low pressure system is expected to move through the Ohio Valley through tonight. In the wake of this system, high pressure is expected to build in for the rest of the week. && .NEAR TERM /Today and Tonight/... Issued at 301 AM EST Mon Dec 16 2019 Radar loop and short term model data indicate the steadier snow should continue to diminish across the area over the next few hours. Should be a break in the more significant precipitation for a period this morning, however surface observations indicates there may be areas of drizzle or freezing drizzle around for much of the morning hours. Organized lift from the next wave currently over the southern Plains is progged by the short term models to begin moving into the southwest zones by early this afternoon, aided by a 40-50 kt low level jet nosing into southern Kentucky. Will go with chance PoPs for mixed precipitation this morning, and go with high PoPs during the afternoon hours. Forecast soundings suggest the elevated warm layer will reach into the southern zones later today, but probably not much farther than that. As a result, will lean towards more of a rain or mixed precipitation over about the southern third of the area, with mostly snow farther north. Will keep PoPs rather high well into the night tonight, as models suggest a deformation zone may set up over the area for a period later tonight. Given developing cold advection and lowering thicknesses, mixed precipitation should tend to change over to snow over the southern zones during the night. Appears there is potential for an additional 2-4 inches of snow later this afternoon and tonight over parts of the area. Reports indicate that some of the central zones have already received around 4 inches from the previous wave. May upgrade the advisory to a warning for a period this afternoon and tonight over some of the central zones, given what has already fallen, expected additional accumulations, and the fact that heavier snow will impact the evening commute. Otherwise, due to the areas of freezing drizzle expected to linger this morning, will keep the advisory as is. Due to thick cloud cover and expected precipitation, will shave a couple of degrees off of the GFs MOS highs today. The guidance lows tonight look OK. && .SHORT TERM /Tuesday through Wednesday Night/... Issued at 301 AM EST Mon Dec 16 2019 Generally dry conditions expected during this period, as surface highs pressure slides through the local area. May leave a lingering PoP for light snow over the eastern zones Tuesday morning to cover any activity that may in the process of exiting the local area. Progged low level thicknesses suggest the GFS MOS highs for Tuesday may be too cool. Will cut about a category off of the guidance highs in that period. The remainder of the periods look OK for now. && .LONG TERM /Thursday through Sunday/... Issued at 301 AM EST Mon Dec 16 2019 High pressure will remain the predominant weather feature through much of the extended period with dry conditions and quiet weather anticipated. A few disturbances aloft will track across the Great Lakes Friday into Saturday but in the absence of stronger forcing aloft and deeper moisture...expect just an increase in clouds over the area as these system pass by to the north. After the midweek chill...temperatures will recover to near to even slightly above normal levels into the weekend. Highs in the lower and mid 30s Thursday will rise into the lower and mid 40s by the weekend. && .AVIATION /Discussion for 160900Z TAF Update/... Issued at 301 AM EST Mon Dec 16 2019 Minor adjustments are in order based on current obs but overall TAFs have the situation well in hand. While snow has largely ended...IFR conditions and lower linger and will likely continue to do so for the next few hours. 06Z discussion follows. Snow bands are moving off to the northeast. Should still see snow at KLAF and KIND for another hour (KIND) or two (KLAF) before snow transitions to a wintry mix of snow, sleet and freezing drizzle at KIND and then just freezing drizzle, and ends altogether at KLAF. KHUF and KBMG should continue to see off and on freezing drizzle for a couple of hours before enough dry air arrives to bring precip to an end. Ceilings should remain IFR or lower through the overnight for the most part, but cannot rule out a brief period where the dry air mixes out the lower ceilings before they build back in at IFR or lower through all of Monday. Snow should move back in Monday afternoon. Winds will generally be northeasterly around 7 to 10 kts through the period. && .IND WATCHES/WARNINGS/ADVISORIES... Winter Weather Advisory until 7 AM EST Tuesday for INZ021- 028>031-035>049-051>057-060>065-067>072. && SYNOPSIS...JAS NEAR TERM...JAS SHORT TERM...JAS LONG TERM....Ryan AVIATION...CP/Ryan
