UPDATE. The LONG TERM Section has been updated below.
SYNOPSIS. Issued at 153 AM EST Sat Feb 27 2021
A warm front will approach and settle across Indiana today . bringing dry weather for today. Tonight more rain will return as an upper level weather disturbance pushes through the Ohio Valley. This will be followed by a cold front pushing across Indiana on Sunday morning . bringing more chances for rain.
Dry weather is then expected to build across the area on Sunday afternoon through at least Wednesday as strong high pressure is expected to be moving slowly through the region. More chances for rain may return late next workweek. Look for above normal temperatures for most of the next seven days.
NEAR TERM /Today/. Issued at 153 AM EST Sat Feb 27 2021
Surface analysis early this morning shows high pressure in place over Florida and low pressure in place over the upper midwest. This was resulting in a SW surface flow across Indiana. GOES16 shows a stream of tropical moisture . streaming across TX to Indiana and Ohio. Radar shows some scattered light rain showers across the area pushing across Indiana within this flow.
Models today suggest that the short wave and isentropic lift currently responsible for this morning early rain will exit Central Indiana by 12Z HRRR allow this wave to exit east. while keeping the deeper moisture with the previously mentioned upper flow farther south across TN and eastern KY. Forecast soundings and time heights through the day trend toward a dry column through the day with subsidence in place. Thus will trend toward a dry forecast today . along with partly cloudy skies. Given our expected SW flow and ongoing warm air advection will trend highs at or above the NBM.
SHORT TERM /Tonight through Monday Night/. Issued at 153 AM EST Sat Feb 27 2021
GFS suggests strong Isentropic lift returns across Central Indiana tonight By 06Z Sunday. the 295K GFS isentropic surface shows excellent up glide with specific humidities over 6 g/kg. Forecast soundings show deep saturation arriving across the area at that time with warm air advection within the lower levels and pwats surging over 1 inch. Further support is seen within the upper levels as a short wave approaches Indiana within the tropical plume of moisture that will be in place across the Ohio Valley. Finally a favorable LLJ appears to be moving across Indiana and KY . around 70 knts through the night. Thus confidence is high for rain showers overnight . especially across the southern parts of the forecast area where dynamics are best. Will trend highest pops there . trending toward less pops farther north. Given the expected clouds and precip will trend lows at or above the NBM.
As the short wave and LLJ departs on sunday morning the 295K Isentropic surface shows lift is lost. Meanwhile surface low pressure will be moving through the Great Lakes and the GFS and Nam suggest as cold front will be sweeping across Indiana through the Day. This still will result in some rain chances early on ahead of the cold front on Sunday morning . however the overall theme of the day will be trending toward drying. Westerly winds in the wake of the front will arrive in the afternoon along with subsidence as suggested with the forecast soundings. Thus will stick close to the NBM pops during the AM hours . but trend toward a dry forecast by afternoon in the wake of the front.
On Sunday night through Monday night strong high pressure over the plains states is depicted to build across Indiana and the Great Lakes as ridging aloft over the northern plains provides lee side subsidence to the upper midwest and southern Great Lakes. Forecast soundings show a very dry column through this period. Thus will trend toward partly cloudy weather on Sunday night through Monday night and will not stray far from the NBM on Temps.
LONG TERM /Tuesday through Friday/. Issued at 320 AM EST Sat Feb 27 2021
At least moderate confidence continues for a pleasant mid to late week as mid-level heights rise into a zonal/flat ridge pattern over most of the US. Generally dry conditions are expected as weather makers consequently retreat to southern Canada . or stay mainly south of central Indiana. Slight chances to chances of light rain or a rain/snow mix exist for the PM hours Tuesday as a potential system crosses the Tennessee Valley, although confidence in precipitation is low.
A greater rain potential surrounds the Thursday Night-Friday time frame when (only) the operational GFS still brings a rather slow cut-off system from Colorado to the southeastern US . which could place ample rainfall over our region courtesy a fetch straight out of the warming Gulf. Most of the GFS ensembles have light/moderate rainfall across Indiana, although the members with strongest phasing keep rain south of the CWA . and the overall trend since yesterday appears to be for weaker gradients/QPF across our realm. All considered, the Blend's slight chance POPs along southern counties were accepted for the time being.
Otherwise the period should be a solid start for March with generally modest winds under partly to mostly clear skies. Temperatures will moderate from near normal to above normal values.
AVIATION /Discussion for 270600Z TAF Issuance/. Issued at 1142 PM EST Fri Feb 26 2021
IMPACTS: Ceiling restrictions will develop quickly this evening with widespread IFR/LIFR ceilings through Saturday morning. Periodic light showers are possible overnight with MVFR visibilities at times. Improvements back to VFR by midday Saturday through the afternoon. Low ceilings will return around or just after the end of the forecast period Saturday night in steady rainfall.
DISCUSSION: Lower ceilings are rapidly advecting into central Indiana from the southwest and should encompass the terminals by mid to late evening with IFR/LIFR levels for the overnight and Saturday morning. Scattered light rain showers will drift across the terminals tonight as well with periodic MVFR visibilities.
Deeper moisture will quickly shift east Saturday morning as a small are of high pressure expands into the region with drier air and subsidence. Clouds will scatter by midday with sunshine for the afternoon. The high will quickly shift off to the northeast Saturday evening with deep moisture returning with a warm front from the south. Steady rain and low ceilings will advect back across all but KLAF around or shortly after midnight Saturday night.

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.
