Fxus63 kiwx 221810 afdiwx area forecast discussion national weather service northern indiana 210 pm edt Mon jul 22 2019 Synopsis Issued at 450 am edt Mon jul 22 2019 expect decreasing cloud cover today into tonight, with highs in the 70s and overnight lows in the 50s. Isolated rain showers are possible through late morning. Otherwise, life-threatening conditions are expected on lake michigan. High wave action will cause dangerous currents, beach erosion, and lakeshore flooding. See the latest statement for more information. There is a chance for showers and thunderstorms Tuesday, but otherwise it will be dry through Saturday. Highs will be in the upper 70s and low 80s through Thursday, then we'll rise back into the mid to upper 80s and low 90s Friday into Sunday. Short term (this evening through Tuesday) issued at 200 pm edt Mon jul 22 2019 latest surface analysis shows cold front along ohio river valley with high pressure centered over the dakotas. Satellite radar still indicating plenty of post-frontal cloud cover over much of the area and a few lingering showers along southern CWA border. Not much change in the short term as surface high to remain displaced to the west of our area which will maintain cool dry northwest flow. Amplified upper level pattern has ridge centered over the four corners with axis extending through the southern provinces of canada while upper low just east of hudson bay with trof axis extending through the great lakes down to the oh tn valley which will maintain NW flow aloft as well. Latest vis satellite imagery showing clearing over far NW CWA and expected to spread southeast through the remainder of the CWA this evening as upper trof axis pivots through the area with ample subsidence and drying behind it. Dewpoints will continue to fall reaching the lower 50s overnight and bring low temps to a refreshing mid 50s. Dry airmass and low level thermal trof shifting eastward should result in just scattered diurnal CU on Tuesday. A weak disturbance dropping down in NW flow will bring a non-zero precip chance to ne CWA Tuesday afternoon but only an isolated shower or two at best. Very comfortable temps for this time of year with highs in the upper 70s to near 80f. Long term (Tuesday night through Monday) issued at 200 pm edt Mon jul 22 2019

quiet weather pattern to continue through much of the long term period. Upper trof axis shifts further east but northwest flow pattern maintains over the region with upper ridge centered over the four corners. Surface high pressure builds into the region maintaining sunny skies and low humidities through Thursday. Northern extent of upper ridge will break down as pacific energy comes onshore Tuesday night. This disturbance will track across southern canada before dipping into the northern great lakes region heading into the weekend. Surface high pressure will move toward the eastern seaboard as well resulting in a developing return flow ahead of this system which will bring an increase in humidity and nudge highs back into the mid-upper 80s this weekend. Forcing will be displaced well to the north of our area and lacking deep moisture return from the gulf will have weekend staying mainly dry with weak signal from ensemble mean and only a couple individual members showing measurable precip in northern cwa. Precip chances not expected until beginning of next week with arrival of surface boundary.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
