Short Range 12/5/12
Beginning Wednesday, December 5, 2012.
High temperatures Wednesday will reach the low to mid 40s for the northern half of Indiana. Southern Indiana will reach temperatures near 60 this afternoon.
Low temperatures tonight will most likely range from the mid 20s to low 30s. The warmer low temperatures will be in the southern region of Indiana. Thursday, temperatures look to warm to the low 60s for the southern region and low 40s for the extreme northern portion of the state. The rest of the state appears to be in the upper 40s for high temperatures.
Friday, a developing cold front that will push through Saturday will most likely cause some rainfall in much of Indiana. Temperatures look to be too warm for snow at this time. Some forcings for this precipitation are a weak vorticity maximum with very little positive vorticity advection. A weak upper level jet stream with little upper level divergence could cause slight upward acceleration. There also appears to be little temperature advection during the time of the rainfall.
