Synopsis
Issued at 245 am edt Mon mar 18 2019
quiet weather will persist through much of this week with
temperatures slowly returning to normal. The only chance of rain
will be on Wednesday as a pair of weak upper level disturbances
cross the region.

Short term (today and tonight)
issued at 245 am edt Mon mar 18 2019
benign weather anticipated for the short term and beyond given
persistent dry W NW flow. Tail end of cyclonically sheared shortwave
passes the area later today and this could touch off a stray
sprinkle in our northern zones given modest low midlevel lapse
rates. However... Profiles are very dry with pw values clocking in at
a tepid 0.2 inches. Weak forcing in such an environment is unlikely
to generate anything more than some increased cloud cover and have
kept the forecast dry. Increased clouds and resident thermal
trough lack of any meaningful WAA will keep highs in the low 40s.

Clouds decrease overnight but model rh fields indicate some sct
midlevel clouds may remain... Keeping lows in the mid upper 20s
despite nearly calm winds.

Long term (Tuesday through Sunday)
issued at 245 am edt Mon mar 18 2019
highly amplified noam pattern with blocking ridge to our west and
persistent troughing to our east will maintain generally NW flow and
quiet weather locally. Only features of note will be shortwave
currently over saskatchewan that will dive into the central plains
by Tuesday night and eventually phase with shortwave digging into
the great lakes wed. This leads to a brief period of more wsw flow
late Tue into Wed with downstream upper level confluence maintaining
high pressure over the eastern seaboard. Result is a local increase
in lower level theta-e ahead of a weak cold front associated with
passing waves. Models have struggled with evolution of these waves
but are trending toward a solution more conducive for light rain in
our CWA Wed and latest pop forecast reflects that. Outside chance
for a few snowflakes at the very onset Wed morning but degree of waa
(and highly marginal temps to begin with), along with diurnal timing
will lead to primarily rain. Rain amounts will also be light (around
a tenth at best) given weak forcing and lackluster moisture
instability. That is about as exciting as this forecast gets.

Dry conditions return for the end of the week. Temps gradually
moderate as longwave ridge axis finally passes our longitude over
the weekend. Returning southerly flow will support much warmer
conditions and chances for rain heading into early next week but the
details remain highly nebulous at this time.

Aviation (for the 12z tafs through 12z Tuesday morning)
issued at 610 am edt Mon mar 18 2019
quiet aviation weather this period withVFR conditions expected.

Some patchyVFR low clouds across northwest indiana this morning
should increase in coverage later this morning into this afternoon
due to sheared short wave dropping southeast form western great
lakes and steep low level low level lapse rates. Light winds this
morning should increase to 10 knots or less this afternoon with
diurnal mixing. Departure of low level ridge axis this evening
will result in backing of winds to southwest with speeds
diminishing to less than 5 knots.

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.
