Area Forecast Discussion National Weather Service Indianapolis IN 651 PM EST Mon Jan 22 2018 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 325 PM EST Mon Jan 22 2018 Low pressure will move into the Great Lakes tonight, bringing additional chances for showers to the area into Tuesday. Aside from a chance of flurries with an upper level wave on Wednesday, dry weather will then dominate through the remainder of the work week. Another frontal system will bring precipitation chances back to the area for the weekend. && .NEAR TERM /Tonight and Tuesday/... Issued at 325 PM EST Mon Jan 22 2018 After widespread rain earlier along a prefrontal trough, the area is mostly dry at this point. However, the main cold front will move into the area tonight along with the upper wave, and showers will likely redevelop, especially late. A few snowflakes cannot be ruled out late tonight into Tuesday, mainly north, but no accumulation is expected. Expect temperatures somewhat steady early then dropping more quickly late as the front moves in. Temperatures tomorrow will climb little if at all. && .SHORT TERM /Tuesday Night through Thursday/... Issued at 325 PM EST Mon Jan 22 2018 The short term looks to be dry as surface high pressure moves into the Tennessee Valley to shut down the majority of precipitation. However, an upper level wave moving through the area Wednesday may spark some flurries, perhaps with sprinkles south. The main impact will be to increase cloud cover, however. Consensus temperatures appeared reasonable throughout with only minor tweaks. Temperatures will be near seasonal normals early, climbing above normal again by Thursday. && .LONG TERM /Thursday Night through Monday/... Issued at 225 PM EST Mon Jan 22 2018 ECMWF suggests strong ridging aloft and surface high pressure across the area on THursday night and Friday which should lead to dry weather is seasonable temperatures. Models suggest the ridge aloft slides east by Saturday and a return flow of warmer and more moist air begins to arrive across Indiana. Meanwhile the ECMWF suggests a deep trough developing in the central plains with ample dynamics, This feature looks to pass across Central Indiana Saturday through Sunday Night along with an associated cold front. This will be the best chance for precipitation within the long term part of the forecast and pops inserted by forecast build appear reasonable. ECMWF then suggests high pressure builds across the area on Monday...but the patter aloft prevents much in the way of an arctic intrusion. Thus dry and seasonal weather will be expected again on Monday. && .AVIATION /Discussion for the 23/00Z TAF Issuance/... Issued at 639 PM EST Mon Jan 22 2018 Strong southwest winds will linger into tonight with sustained speeds of 12 to 14 kts and gusts up to 22 kts. Meanwhile, conditions will generally be at VFR levels for now. However, wraparound moisture is approaching on the back side of a low pressure system spinning over Illinois. As rain chances increase tonight, ceilings will deteriorate to MVFR (or worse) levels by Tue 08Z. They will then hover around the MVFR level through the end of the TAF period. && .IND WATCHES/WARNINGS/ADVISORIES...NONE. && SYNOPSIS...Nield NEAR TERM...Nield SHORT TERM...Nield LONG TERM...TDUD AVIATION...TDUD
