Area Forecast Discussion National Weather Service Northern Indiana 639 AM EST Fri Jan 24 2020

SYNOPSIS. Issued at 440 AM EST Fri Jan 24 2020

Periods of light rain will continue early this morning with temperatures around 35 to near 40 through today. Light accumulating snow is likely tonight, especially west of Highway 31 where 1 to 2 inches are expected, especially on grassy areas. Additional chances for rain and snow showers are expected through Sunday morning with little if any accumulation before a period of dry weather returns.

SHORT TERM. (Today through Saturday night) Issued at 406 AM EST Fri Jan 24 2020

An upper low was over the Ozarks with an associated surface low over central Missouri early this morning. Weak warm air advection overnight has helped the low levels to warm enough to end the wintry mix of rain with some snow and sleet last night. The upper low will drift north today and will continue to bring periods of light rain to the forecast area, although breaks in the rain are most likely near Monticello as the dry slot attempts to move into the area. The core of the upper low will move across northern Indiana tonight. Low level thermal fields will fall below freezing and will support rain changing to snow. It looks like 1 to 2 inches of snow is likely by mid Saturday morning given isentropic lift on the 295K surface, especially on grassy areas west of Highway 31 as the deformation zone moves over the area. It appears travel issues will be limited with pavement temperatures remaining above freezing. The low will move north into Lower Michigan with chances for light rain and snow continuing through Saturday; however, little if any additional snow accumulation is expected after noon Saturday

LONG TERM. (Sunday through Thursday) Issued at 406 AM EST Fri Jan 24 2020

For Sunday through Thursday little if any precipitation is expected with seasonably mild temperatures for this time of year. Highs should be from around 35 to 40 each day with lows from the mid 20s to lower 30s each night. Most noticeable will be the absence of arctic air with the continued pattern of above normal temperatures (Fort Wayne has only had 3 days the temperature has been below normal during the past nearly 5 weeks).

AVIATION. (For the 12Z TAFS through 12Z Saturday Morning) Issued at 635 AM EST Fri Jan 24 2020

Widespread light rain/drizzle continues this morning although some break in coverage intensity has developed over past few hours. Renewed low level moisture transport surge is expected from the Ohio Valley over the next several hours however, as an upper jet streak rounds the base of the upper trough. This will support expanding rain coverage later this morning, particularly across northeast Indiana impacting KFWA. Cigs/vsbys will continue to deteriorate as terminals remain north of a northward advancing occluded front through early evening. Have trended terminals to IFR/LIFR conditions today into this evening with little to no opportunity for substantial improvement this forecast valid period. Low level cold core moves in Saturday morning which should change precip to rain/snow mix later this evening and to a period of snow toward end of this forecast valid period as a stronger vort max rotates through the parent upper level system across the southern Great Lakes.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
