* High Wind Warning late tonight into Thursday north
* Wind Advisory south
* Heavy rain possible tonight

This Afternoon into Tonight

Generally quiet conditions continue this afternoon ahead of an 
approaching storm system that will arrive this evening. Latest 
observations show clouds continuing to increase in coverage and 
thickness. Some rain has been noted on the Evansville radar just now 
starting to enter Knox County. The rain is expected to gradually 
spread northward for the remainder of today, reaching Indianapolis 
around 7pm or so. 

Rain could become heavy at times during the night, with high-res 
models hinting at some embedded convective activity along the 
system's warm front. A potent 850mb jet upwards of 75kts is expected 
to develop overnight, with robust warm air and moisture advection 
leading to strong frontogenesis along the nose of the developing 
jet. Model soundings show elevated instability developing after 06z, 
rooted around 850mb, as WAA substantially increases the warm nose 
and steepens mid-level lapse rates. PWAT values of over 1.25 inches 
exceeding the 90th percentile for this time of the year, strong 
convergence along the warm front, along with instability aloft 
should lead to a period of intense rainfall rates. An inch or two of 
rain may fall in a 2 to 4 hour period, confined to a rather narrow 
band extending along the front - roughly from Terre Haute to 
Indianapolis. Isolated flooding is possible if amounts exceed 2 
inches, but the threat is low enough to preclude a flood watch at 
the moment.

Once the warm front lifts northward, rain and thunderstorms should 
become more scattered in nature. An isolated strong to severe wind 
gust is possible with any thunderstorm, as very strong LLJ winds 
will be just above the surface. However, model soundings continue to 
indicate a low level inversion through the night, thus limiting the 
threat for severe thunderstorms. The best chance could be any 
convection out ahead and along the system's approaching cold front.

Temperatures should rise into the 50s overnight as the warm front 
passes to our north and WAA takes hold. Non-thunderstorm surface 
winds should begin to increase towards morning as the system deepens 
and strengthens the MSLP gradient across the region.


Thursday morning, the low will continue to deepen within a highly 
dynamic environment and strong baroclinic zone. This will lead to a 
further steepening pressure gradient over central Indiana. Rain 
showers will exit to the NE Thursday morning in front of a dry slot. 
A few thunderstorms will still be possible over N/NE central Indiana 
ahead of the front, and convective mixing could lead to an isolated 
high wind gust prior to the start of the High Wind Warning. 

Within the dry slot non-thunderstorm winds become a concern with the 
lower level lapse rates steepening and increasing the mixing depth. 
The LLJ will be slightly weaker than the pre-frontal jet, but with 
he low continuing to deepen, 1km winds of 60-70kts will be likely. 
As the PBL expands in the drier air, vertical mixing should be able 
to tap into this LLJ, leading to wind gusts of 55MPH or greater. 
This has lead to a High Wind Warning for locations north of I-70, 
where 1km winds will be strongest near the center of the low. Strong 
wind gusts will still be likely for all of central Indiana, but the 
magnitude is expected to be less (45-55MPH). 

The cold air should remain well NW of central Indiana with the DCB 
limiting its southward extend, but still a steady drop in 
temperatures are likely within the dry slot. This should lead to 
afternoon highs in the mid to upper 40s, down from upper 50s to low 
60s in the morning. Winds should begin to die down overnight as the 
low passes to the NE and a developing diurnal inversion, ending the 
wind threat around dusk.

Historical Weather And Climate Facts For Today
A severe cold wave gripped the southeastern U.S. The mercury dipped to 8
above at Jacksonville FL, and to zero at Savannah GA. Orange trees were
killed to the roots. (David Ludlum)
The temperature at Denver CO plunged to a record 30 degrees below zero.
(David Ludlum) (The Weather Channel)
A powerful storm produced blizzard conditions in the Great Lakes Region.
Winds gusted to 86 mph at Janesville WI and Cleveland OH received 12 inches
of snow. North winds of 50 to 70 mph raised the water level of southern
Lake Michigan two feet, and produced waves 12 to 18 feet high, causing
seven million dollars damage along the Chicago area shoreline. It was the
most damage caused by shoreline flooding and erosion in the history of the
city of Chicago. (The National Weather Summary) (Storm Data)
