UPDATE. The AVIATION Section has been updated below.
SYNOPSIS. Issued at 147 AM EST Thu Dec 5 2019
Another dry and pleasant day is in store for Central Indiana today along with more dry weather this evening as high pressure in place across the deep south slowly exits to the east.
Late tonight an area of low pressure is expected to push into the Tennessee River Valley from the southern Plains. This system will bring chances for rain to southern Indiana late tonight and early on Friday.
High pressure is then expected to settle across the region by Friday afternoon . brining dry and pleasant December weather through Saturday. Rain chances will return on late Sunday and Sunday night. Then there is another chance of rain Monday, turning to snow Monday night. Could see some accumulations Monday night through Tuesday . along with much colder temperatures on Tuesday.
NEAR TERM /Today/.
Issued at 147 AM EST Thu Dec 5 2019
Surface analysis early this morning shows high pressure over LA/Mississippi . with ridging extending north to Illinois. This was resulting in a cool NW flow across Indiana. Surface low pressure was in place near the Texas panhandle. GOES16 shows clear skies across Indiana within the NW flow.
Models today continue to keep a quick NW flow in place aloft . slowly transition to a W-NW flow through the day. Little to no dynamics are expected to pass within the flow aloft today. Meanwhile at the surface . the high pressure system to the south and the associated ridging is expected to pass across Indiana by mid day . allowing a warmer southerly flow to develop. Models evening suggest some warm air advection in play on the back side of the departing ridge this afternoon. Forecast soundings and time heights continue to suggest a dry column today . with perhaps only some high . thin clouds flowing within the quick flow aloft. Thus will trend toward a partly cloudy sky today along with temps at or above the NBM.
SHORT TERM /Tonight through Saturday night/.
Issued at 147 AM EST Thu Dec 5 2019
GFS and NAM continue to suggest a short wave will push out of the southern plains tonight and push across the deep south late tonight before exiting the area on Friday Morning. A surface low is associated with this system . also staying south of Indiana. Best moisture and forcing late tonight and early Friday appear to stay contained well south of Indiana with our southern forecast area really on the cusp. Forecast soundings remain dry across the northern parts of the Forecast area . but appear more saturated the farther south one progresses. Moisture really remains a issue with the quick moving system . as the gulf never really has time to open up Thus confidence is low for rain. but small chance pops still appear warranted across the Vincennes-Bedford-Seymour areas late tonight and early on Friday. Will trend lows tonight at or above the NBM given the expected clouds and possible precip.
THe models depict high pressure quickly building across Indiana from the northwest on Friday afternoon as the low and short wave quickly depart to the east. Forecast soundings show strong subsidence and drying within the column on Friday afternoon and night. Dry air is expected to persist through Saturday as northwest flow persists aloft ushering more Pacific air into Central Indiana. Thus dry weather will be expected from Friday night through Saturday night.
LONG TERM /Sunday through Thursday/.
Issued at 304 AM EST Thu Dec 5 2019
The early portion of the period will be fairly active with chances for rain Sunday through Tuesday with high pressure building Wednesday into Thursday. An upper level trough is forecast to strengthen early next week with an associated surface front that is expected to move through central Indiana Monday night. Chances for rain begin as early as Sunday and Sunday night as southerly winds advect seasonably warm and moist air which will interact with some weak forcing aloft. More widespread rain will move in Monday night into Tuesday with stronger forcing from the aforementioned surface cold front.
Current thoughts are the best chances for rain will be late Sunday into Monday when forcing out ahead of the front is expected to be strongest. The heaviest axis of rain will likely end up south of the forecast area, but will be dependent on where the strongest forcing set up. Small chances for rain continue into Tuesday with a possibility for a rain/snow mix during the day Tuesday. Confidence is low for any snow Tuesday with the thought that precipitation will likely exit before temperatures drop enough to generate snow. Temperatures are expected to plummet during the day Tuesday with the high temperature likely before sunrise. Conditions will be dry Wednesday and Thursday with strong cold air advection bringing the coldest temperatures of the period.
Temperatures are expected to be above average Sunday and Monday with below average temperatures Tuesday to Thursday.
AVIATION /Discussion for the 05/18Z TAF/.
Issued at 1235 PM EST Thu Dec 5 2019
Conditions will start out VFR through most of today. Late tonight through midday tomorrow, ceiling conditions will deteriorate to MVFR as low ceilings move in with a surface low pressure system. Could see wind shear issues in the overnight hours at some sites.
Mostly clear skies through the rest of today. A surface low pressure system moving eastward and centered south of the area will bring clouds, with MVFR ceilings, to the area for the overnight hours through midday tomorrow. Could see wind shear at times overnight ahead of the system. Slight chance of rain is possible mostly south of the TAF sites. Winds will start out from the south and transition to northerly by tomorrow morning. Surface wind speeds will mainly be 5 to 10 kts gusting to 15 to 20 kts.

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.
