9/1/2012 8:00 AM 0.78 M M M M Rainfall from Isaac; rain began yesterday afternoon (8/31/12) at 4 pm CDT. Rainfall band has moved north of Macomb, but additional showers are developing further south and expected to rotate through the area later today.
9/2/2012 10:00 AM 0.48 M M M M Heavy rainbands missed Macomb on Saturday, 1 September 2012. Showers popped up to the southeast and east, rotating around the low pressure center in Missouri. Some of these storms became tornadic, with tornadoes sighted near Smithfield (east of Macomb) and further to the ENE north and east of Peoria, including one by Chillicothe.
9/3/2012 10:00 AM 0.16 M M M M Scattered showers developed from solar heating of the remnant tropical moisture from former Hurricane Isaac, rotating from NE to SW, since the low was located S/SE of Macomb.
9/4/2012 10:00 AM 0.00 0.0 M M M A Trace of precipitation occurred overnight from a band of showers and storms that moved southeast out of central and southern Iowa. The northern area largely dissipated before reaching Macomb, east of the Mississippi River.
9/5/2012 10:00 AM 0.21 M M M M Line of thunderstorms moved through early this morning shortly after 6 am.
9/6/2012 9:00 AM 0.00 0.0 M M M Severe weather potential anticipated for the region failed to develop despite ample CAPE in the absence of sufficient forcing despite the passage of a dry cold front.
9/7/2012 10:00 AM 0.07 M M M M Storm development occurred at the end of a cluster (MCS) of storms moving across the northern half of Illinois.
9/8/2012 9:00 AM 0.10 M M M M Line of showers which developed ahead of a cold front moved through the Macomb area late Friday afternoon.

9/13/2012 9:00 AM 0.00 0.0 M M M Cold front passed through the Macomb area earlier this morning, shortly before 6 am. All precipitation is occurring behind the front, with a weakening band of showers slowly approaching from the northwest, but still not expected to arrive until early afternoon. It now appears that widespread rainfall of significance will not materialize, with less than a tenth of an inch now in the NWS forecast based on radar trends and weakening upper level support.
9/14/2012 12:00 PM 0.17 M M M M Sorry this is late. A band of showers behind a cold front moved through the Macomb area during the late afternoon and early evening hours.

9/17/2012 9:00 AM 0.00 0.0 M M M Radiation (ground) fog developed overnight, leaving the ground wet from the fog and heavy dew deposited. Fog has since dissipated leaving cloudy skies as a strong cold front approaches from the northwest, bringing us a definitive taste of fall!
9/18/2012 10:00 AM 0.03 M M M M A strong cold front moved through the Macomb area late yesterday afternoon, spawning a broken line of scattered showers and thunderstorms along the boundary. Storms to the west of us fell apart, with heavy rain located to our north. A second area of light rain behind the front then moved through later, but as you can see, rainfall amounts were not terribly impressive. Skies cleared before midnight, allowing morning temperatures to bottom out in the mid 40's, held up by sufficient mixing by NW winds.
9/19/2012 8:00 AM 0.00 0.0 M M M With clear skies, dry air, and calm winds, temperatures dropped quickly last night, reaching 42 degrees by midnight. However, weak southerly flow commenced, with associated warm advection resulting in temperatures holding steady through the remainder of the night until rising when winds increased after 6 am.

9/22/2012 8:25 AM 0.03 M M M M Scattered showers and thunderstorms developed Friday afternoon just north of a warm front and a low pressure center (triple point) which later moved right over Macomb. These showers strengthened south and east of Macomb in McDonough County before tracking eastward. Additional development occurred behind the initial storms as the low moved through.
