Updated aviation portion for 18Z TAF issuance

SHORT TERM. Today . Tonight . and Friday Issued at 356 AM CST Thu Dec 12 2019

Winter weather headlines will be the main concern today.

Only minor changes to headline timing, with a later start time for the southern tier of counties, including the northern Fox Valley.

Light snow continued to develop over northern WI, in association with the RRQ of an upper level jet and strong WAA. This initial band of snow was lifting northeast, leaving central WI and the Fox Valley dry at this early hour. Bands of snow are expected to continue to form over northern WI early this morning, though lingering dry air in the low-levels may limit the intensity and result in some breaks in the steady snow at times, especially over the far northeast. The snow is expected to become heavier and more widespread from west to east during the morning as low pressure approaches and the low-level jet cranks up to 40 to 45 knots. A potent short-wave over the Dakotas will provide additional forcing as it moves through the region during the afternoon. The heaviest snow is expected from mid-morning through mid-afternoon. Moisture will shallow out during the mid to late afternoon, leading to the potential for freezing drizzle. Do not think the freezing drizzle will be very impactful, as it will be falling on snow covered or treated roads. Snowfall totals will range from 1 to 3 inches south to 5 to 7 inches north. Highs will range from the upper teens northwest to the lower 30s southeast.

Lingering light snow or freezing drizzle will taper off in eastern WI this evening, with mostly cloudy skies persisting through the night. Lows will be in the teens northwest and lower to middle 20s southeast.

Weak low pressure/inverted trough will approach the region Friday afternoon, and bring a small chance of light snow or freezing drizzle, especially across our western counties. Highs will be in the 20s and lower 30s.

LONG TERM. Friday Night Through Wednesday Issued at 356 AM CST Thu Dec 12 2019

The main highlights for this forecast period are the chances for accumulating snow Friday night through Saturday and below normal temperatures for next week.

Friday Night through Saturday . An upper-level shortwave trough will move into the Upper Mississippi Valley Friday night. Questions then arise with the surface low pressure system/cold front. Model guidance is not in agreement with the track of this system or amount of moisture associated with it, and shows some phasing problems. However, there is some agreement with weak forcing during this time, making for light snow accumulations. Do to much uncertainty with this system, did not steer much from model blend.

Rest of the forecast . By Saturday night, the upper-level trough will shift east leaving behind chances for light lake effect snow showers over far north-central Wisconsin. A surface high pressure system will then push into the northern Plains funneling cold Canadian air into the forecast area. Therefore, temperatures beginning Sunday morning through the rest of the extended will remain below normal. A small break in the below normal temperatures may occur on Monday as model guidance shows a low pressure system moving into the Midwest from Oklahoma on Monday. This system could bring some snow to southeastern Wisconsin, however, models are not in agreement with the track of this system. Beyond this system, another area of high pressure will move into the northern Plains bringing more cold Canadian air to the region through midweek.

AVIATION. for 18Z TAF Issuance Issued at 1201 PM CST Thu Dec 12 2019

IFR conditions and snow are expected in most places through the early evening hours. The snow could end as light freezing drizzle. MVFR or IFR ceilings will continue tonight, with the lowest ceilings north of a AUW to IMT line. Mostly MVFR ceilings are expected Friday, with a chance of light snow in the afternoon in northern and central Wisconsin.

GRB WATCHES/WARNINGS/ADVISORIES. Winter Weather Advisory until 6 PM CST this evening for WIZ005- 010-018>022-030-031-035>040-074.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
