Weather Blog: NWS Conference Call 1/11/19

LOUISVILLE, KY (WAVE) - The National Weather Service in Louisville held a conference call on Friday afternoon to discuss weekend winter weather potential. Notes from the conference call are below.

2:30pm - Conference call will begin shortly

2:31pm - John Gordon, meteorologist in charge, is leading the call today

2:31pm - It will take some time for the atmosphere to saturate, so even though radar echoes will be moving over you, it'll take some time for it to actually snow in your location

2:31pm - The farther north you go, the worse it will get. Winter Storm Warnings. Places like Washington (IN), Scott, and Jefferson (IN) and north from there under a Winter Storm Warning. Rest of us under an Advisory.

2:32pm - Warm air noses in during the day, decreasing snowfall for areas of Southern and Central KY. Higher snow totals north in Southern Indiana.

2:33pm - This is a Southern Indiana event, ultimately. Areas north of I-64 stand the best chance of seeing the most impact.

2:34pm - Perry and Crawford Counties in Indiana could be upgraded to a warning from an Advisory.

2:34pm - Paoli Peaks should be smiling from ear to ear!

2:34pm - School events this evening are fine, but late tonight is when problems begin with snow.

2:35pm - This event will likely start as some light sleet, then go to all wet snow tonight.

2:35pm - Lows below freezing tonight, between 28-31° for most. Those in Southern KY could go above freezing, helping keep snow totals low down there.

2:36pm - 12-7am will be the worst period for snow. UPS will be negatively impacted.

2:36pm - Rain along and south of I-64 during Saturday afternoon. Highs in the 30s (above freezing) during Saturday.

2:37pm - Saturday night and Sunday morning snow event looks less intense as temps will likely be just above freezing for most.

2:37pm - Patchy wintry mix or freezing drizzle possible Sunday night into Monday morning with temps going solidly below freezing. That will need to be watched.

2:38pm - Road crews are already brining. Monday morning is a period to be concerned about given freezing drizzle potential.

2:38pm - It's question and answer time, beginning with Southern Indiana call participants

2:39pm - Question about banding of snow, giving us locally heavier amounts. Some isolated banding is possible in Southern Indiana with this.

2:40pm - Heavier snow in Central Indiana, from Seymour northward. Keep that in mind if traveling north tomorrow!

2:40pm - How much snow will melt? There will be melting throughout Saturday, but temps will be in the 30s above freezing with clouds so it won't be a lot.

2:41pm - West of I-65 in Kentucky questions? None.

2:42pm - East of I-65 in Kentucky questions?

2:42pm - Bryce from Hardin County... How bad is Monday morning and what time frame will road temps be a problem? Road temps will be below freezing Monday morning. John Gordon would at least be slightly concerned. There will be a conference call on Sunday *IF* Monday morning looks bad. It's less clear how that will evolve right now, so not many details at the moment.

2:44pm - City of Louisville Public Works: What time does this arrive? Some light sleet and snow early tonight, but no major impact. After 12am is when the main action arrives, lasting through 6am. Low will be near 30 degrees. Snow rates will increase as the night wears on.

2:48pm - Bullseye of snow for this entire storm will be the St. Louis area. West Virginia also gets pounded in the mountains.

2:50pm - Southern KY? Some brief snow in the morning, but melting in the afternoon and rain later in the day on Saturday. Decent confidence with that setup.

2:51pm - No other questions. The conference call is over.
