FORECAST UPDATED: 5:30 pm Tuesday, Mar 10, 2015 by Tyler Heckstall (firstname.lastname@example.org)
Summary: No winter weather anticipated! Dense fog likely Tuesday night into Wednesday morning. Periods of rain likely Thursday night through Saturday morning across most of state. Overall, temps will remain mild during forecast period.
Currently, there is no winter weather expected over the next seven days! Tonight and through the morning hours Wednesday, dense fog is expected to develop especially in the areas that received rainfall on Tuesday. The weather pattern is relatively stagnant this week, so there are no major features to help produce strong surface winds. The weaker winds, moisture, and high pressure system will help fog development overnight Tuesday. With winds continuing to be weak Wednesday, the fog will be slow to erode during the day and some areas may have fog persist through the early afternoon hours. Fortunately, given the mild temperatures, the surface temperatures are expected to remain above freezing overnight. Patchy areas in the northern districts may fall below freezing, but it will be too sparse to be problematic. By Wednesday afternoon, fog should burn off and give way to partly cloudy skies and high temperatures in the 50s statewide.
High pressure aiding in fog formation Wednesday will begin to push eastward overnight Wednesday. This should keep fog chances low for Thursday morning and numerical models are also showing low level moisture being low as well further validating this prediction. A low system should approach from the south during the day Thursday. This will tend to increase cloudiness from south to north across Indiana Thursday afternoon and evening. Rain should then overspread locations south of I-70 by 8pm EDT and north of I-70 and south of US-30 by 2am EDT Friday. Locations primarily south of US-30 Friday should expect to see occasional rain during the day before the exits Saturday morning.
In wake of Friday's rainmaker, a cold front will move south and keep temperatures slightly cooler across the state for Saturday afternoon. This will also allow dry air to filter in and dry things out by the afternoon hours. A ridge of high pressure is expected to build in for Sunday and bring above normal temperatures and more dry weather. Sunday will likely be the most pleasant day of the weekend.
