Hurricane season officially starts on June 1st but there will be some tropical activity showing up on Sunday and Monday.
Other than that, there's not much else going on. It's a fairly quiet pattern with rain and some thunderstorms but nothing too severe.
Here are the national trends for temperature and precipitation:
Here is the latest from the NWS:
.NEAR TERM /Tonight/... Issued at 251 PM EDT Wed May 13 2020 The thick cloud shield present north of a warm front from the southern Plains into the Tennessee valley continues to expand northeast across the forecast area slowly. Areas north and east of a LAfayette-New Castle line were enjoying a nice but breezy day with abundant sunshine and temperatures in the mid 60s. Over the rest of the forecast area...skies were cloudy with temperatures largely in the 50s. A few light showers continue southeast of the Indy metro. The isentropic lift that is assisting with the light showers will shift east of the area later this afternoon which should further minimize any showers coverage to isolated at best into the evening. The focus will then shift towards the approaching warm front which will lift across the forecast area overnight. Additional isentropic lift will develop and focus over northern counties as the night progresses...otherwise any scattered convection is likely to be dependent on increasing warm advection with the bulk of the better forcing to the northwest of the region. Will focus highest pops in the 06-12Z window as the front lifts through the region. Temps...temperatures are not likely to fall back much this evening with perhaps the exception of the northeast where temperatures may peak in the upper 60s to even near 70 late today before dropping back. As the front passes from south to north late tonight...may see temps rise several degrees prior to daybreak. Mid 50s a good bet for lows and that is handled well by guidance. && .SHORT TERM /Thursday through Friday Night/... Issued at 251 PM EDT Wed May 13 2020 Forecast challenges focus on chances for rain and storms throughout the period as a frontal boundary becomes quasi-stationary over the Ohio Valley and lower Great Lakes. The warm front will shift north into the Great Lakes on Thursday as ridging aloft becomes firmly established across the region and finally...finally brings Spring back to central Indiana after being gone for the last 10 days or so. A noticeably warmer and more humid airmass will settle into the forecast area south of the boundary on Thursday. Could still see lingering scattered convection Thursday morning before activity shifts away to the north with the boundary. Potential exists for some sunshine into the afternoon and with a strong S/SW flow...expect temperatures to skyrocket across the forecast area. Potential for scattered convection to redevelop once again in the afternoon but expect any storms to be largely dependent on available instability and steepening lapse rates through the boundary layer. The primary low level jet will remain focused to the northwest closer to the surface wave tracking into the western Great Lakes and should limit convective coverage into the evening over the forecast area. Robust linear convection is likely to develop ahead of the front extending from northern Illinois back into the central/southern Plains by Thursday evening. The frontal boundary will sag into the region from the northwest late Thursday night likely bringing the remnants of this convective line into the forecast area in a weakened state. A strengthening low level jet nosing into the area should be able to maintain convection all night but With just elevated instability present...expect storms to be largely subsevere with gusty winds...small hail and heavy rainfall as the primary threats. Even as the low level jet moves away to the east on Friday...the front will lag back across central Indiana for much of the day. With plentiful low level moisture and about 1000-1500 j/kg MLCAPE... expect widespread showers and storms periodically throughout the day. Categorical pops are warranted with a gradual shift south into the afternoon and evening as the front presses south. Models are now in good agreement on the front settling south of the Ohio River by early Saturday as weak high pressure over the Great Lakes advects drier and slightly cooler air into the forecast area. Temps...strong warm advection...some sunshine and breezy SW flow all support going above guidance for highs in most areas Thursday. Expect upper 70s and lower 80s across the forecast area. The combination of rain and clouds will keep temps lower Friday but should still see low to mid 70s in many locations. Utilized a model blend for lows Thursday and Friday night. Expect low to mid 60s Thursday night with slightly cooler air Friday night enabling a drop into the mid and upper 50s over the northern half of the forecast area. && .LONG TERM /Saturday through Wednesday/... Issued at 301 PM EDT Wed May 13 2020 Temperatures look to remain similar for the weekend with highs in the 70s and dew points in the low 60s. Overnight Saturday, another weak boundary will progress through, bringing in showers from west to east. Current timing of the surface low is variable. It looks likely that some rain will reach western portions of central Indiana by Saturday evening. Lower confidence in rain to the north and east for much of Saturday. Showers and thunderstorms look likely on Sunday along a quickly progressing cold front. Further updates will aid in pinpointing this weekends rain chances. A period of dry weather does look possible this weekend before and after the trough moves through. Most showers throughout the weekend will be convective in nature given the high surface moisture and decent mid level lapse rates. Weak upper level forcing and shear should limit updraft longevity and therefor lightning. However, instability will be sufficient for convective development, and any sustained updraft will likely be associated with some lightning. For now, the greatest threat for thunderstorms during the long term looks to be Saturday night and Sunday as a better area of low-level dynamics looks to promote updraft development. For Monday, a cooler airmass will build in leading to highs in the mid 60s and overnight lows near 50. By Tuesday however, temperatures look to return into the 70s. Some lingering moisture may wrap around bringing slight chances for rain to the north. High pressure will bring drier conditions for the rest of the long term.
